Field Lacrosse, sometimes referred to as the "fastest sport on two feet," is a full contact outdoor men's sport played with ten players on each team. The sport originated among Native Americans, and the modern rules of field lacrosse were initially codified by Canadian William George Beers in 1867. Field lacrosse is one of three major versions of lacrosse played internationally. The other versions, women's lacrosse (established in the 1890s) and box lacrosse (which originated in the 1930s), are played under significantly different rules.
The object of the game is to use a long handled racket, known as a lacrosse stick or crosse, to catch, carry, and pass a solid rubber ball in an effort to score by ultimately hurling the ball into an opponent's goal. The triangular head of the lacrosse stick has a loose net strung into it that allows the player to hold the lacrosse ball. In addition to the lacrosse stick, players are required to wear a certain amount of protective equipment. Defensively the object is to keep the opposing team from scoring and to dispossess them of the ball through the use of stick checking and body contact. The rules limit the number of players in each part of the field and require the ball to be moved continuously towards the opposing goal.
Lacrosse is governed internationally by the 31-member Federation of International Lacrosse, which sponsors the World Lacrosse Championships once every four years. A former Olympic sport, attempts by the international governing body to reinstate it to the Games has been hampered by insufficient international participation and by the existence of separate governing bodies for the men's and women's versions of the sport until 2008. Field lacrosse is played professionally in North America by the Major League Lacrosse. It is also played on a high amateur level by the National Collegiate Athletic Association in the United States, the Australian Senior Lacrosse Championship series, and the Canadian University Field Lacrosse Association.
Known as the "fastest sport on two feet", lacrosse is a traditional Native American game. According to Native American beliefs, playing lacrosse is a spiritual act used for healing and giving thanks to the "Creator". They would also play the game to resolve minor conflicts between tribes, that were not worth going to war for. Thus the name little brother of war.  These games could last several days and as many as 100 to 1,000 men from opposing villages or tribes played on open plains, between goals ranging from 500 yards (460 m) to several miles apart.
The first Europeans to observe it were French Jesuit missionaries in the St. Lawrence Valley, in the 1630s. The name "lacrosse" comes from their reports, which described the players' sticks as like a bishop's crosier—la crosse in French. The Native American tribes used various names: in the Onondaga language it was called dehuntshigwa'es ("they bump hips" or "men hit a rounded object"); da-nah-wah'uwsdi ("little war") to the Eastern Cherokee; in Mohawk, tewaarathon ("little brother of war"); and baggataway in Ojibwe. Variations in the game were not limited to the name. In the Great Lakes region, players used an entirely wooden stick, while the Iroquois stick was longer and was laced with string, and the Southeastern tribes played with two shorter sticks, one in each hand.
In 1867, Montreal Lacrosse Club member William George Beers codified the modern game. He established the Canadian National Lacrosse Association and created the first written rules for the game, Lacrosse: The National Game of Canada. The book specified field layout, lacrosse ball dimensions, lacrosse stick length, number of players, and number of goals required to determine the match winner.
Women's lacrosse, a non-contact version of the sport originating in Scotland during the 1890s, is played by twelve players per side, on longer fields and with less protective equipment than the men's game requires. In the 1930s Canadian businessmen established a version called box lacrosse to create business for ice hockey arenas during the summer months. Box lacrosse is played indoors, with smaller nets, between two teams of six players, and strongly resembles the game its areas were designed for.
Field lacrosse involves two teams, each competing to shoot a lacrosse ball into the opposing team's goal. A lacrosse ball is made out of solid rubber, measuring 7.75 to 8 inches (19.7–20 cm) in circumference and weighing 5 to 5.25 ounces (140–149 g). Each team plays with ten players on the field: a goalkeeper; three defenders in the defensive end; three midfielders free to roam the whole field; and three attackers attempting to score goals in the offensive end. Players are required to wear some protective equipment, and must carry a lacrosse stick (or crosse) that meets specifications. Rules dictate the length of the game, boundaries, and allowable activity. Penalties are assessed by officials for any transgression of the rules.
The game has undergone significant changes since Beers' original codification. In the 1930s, the number of players on the field per team was reduced from twelve to ten, rules about protective equipment were established, and the field was shortened.
Playing area 
Field lacrosse goals are centered between each sideline, positioned 15 yards (14 m) from each endline and 80 yards (73 m) apart from one another. Positioning the goals well within the endlines allows play to occur behind them. The goal is 6 feet (1.8 m) wide by 6 feet (1.8 m) tall, with nets attached in a pyramid shape. Surrounding each goal is a circular area known as the "crease," measuring 18 feet (5.5 m) in diameter.
If a player enters the "crease" while shooting toward the goal, the referee will call a foul and the ball gets turned over to the other team.
A pair of lines, 20 yards (18 m) from both the midfield line and each goal line, divides the field into three sections. From each team's point of view, the one nearest its own goal is its defensive area, then the midfield area, followed by the attack or offensive area. These trisecting lines are called "restraining lines." A right angle line is marked 10 yards (9.1 m) from each sideline connecting each endline to the nearer restraining line, creating the "restraining box." If an official deems that a team is "stalling," that is not moving with offensive purpose while controlling the ball, the possessing team must keep the ball within the offensive restraining box to avoid a loss-of-possession penalty.
Field markings dictate player positioning during a face-off. A face-off is how play is started at the beginning of each quarter and after each goal. During a face-off, there are six players (without considering goalkeepers) in each of the areas defined by the restraining lines. Three midfielders from each team occupy the midfield area, while three attackmen and three of the opposing team's defensemen occupy each offensive area. These players must stay in these areas until possession is earned by a midfielder or the ball crosses either restraining line. Wing areas are marked on the field on the midfield line 10 yards (9.1 m) from each sideline. This line indicates where the two nonface-off midfielders per team lineup during a face-off situation. These players may position themselves on either side of the midfield line. During a face-off, two players lay their sticks horizontally next to the ball, head of the stick inches from the ball and the butt-end pointing down the midfield line. Once the official blows the whistle to start play, the face-off midfielders scrap for the ball to earn possession and the other midfielders advance to play the ball. If possession is won by the face-off player, he may move the ball himself or pass to a teammate.
The rules also require that substitution areas, a penalty box, coaches area, and team bench areas be designated on the field.
A field lacrosse player's equipment includes a lacrosse stick, and protective equipment, including a lacrosse helmet with facemask, lacrosse gloves, and arm and shoulder pads. Players are also required to wear mouthguards and athletic supporter.
Each player carries a lacrosse stick measuring 40 to 42 inches (1.0–1.1 m) long (a "short crosse"), or 52 to 72 inches (1.3–1.8 m) long (a "long crosse"). In most modern circles the word "crosse" has been replaced by "stick" and the terms short stick, and long stick or pole are used. The term "crosse" is still used is in the rulebook and in reference to a crosse check (a check where ones hands are spread on the crosse and the checker extends his arms into the checkee). On each team up to four players at a time may use a long crosse: the three defensemen and one midfielder. The lacrosse stick, or crosse, is made up of the head and the shaft (or handle). The head is roughly triangular in shape and is loosely strung with mesh or leathers and nylon strings to form a "pocket" that allows the ball to be caught, carried and thrown. In field lacrosse, the pocket of the crosse is illegal if the top of the ball, when placed in the head of the stick, is below the bottom of the stick's sidewall. The head of a crosse may be 10 inches (25 cm) in length. The maximum width of the head across the top is 4 to 10 inches (10–25 cm), for international competition, or 6.5 to 10 inches (17–25 cm) according to NCAA regulations. The NCAA instituted stricter specifications to ensure the "safety and integrity of the game." As the shape of the crosse evolved, dislodging the ball from an opponent's crosse became more difficult, and defenders used an increased amount of force when checking. The rule change was intended to reduce injuries, as defenders would need less forceful checks in order to dispossess opponents. Beginning January 1, 2010, measurements for the crosse shall include the following, in addition to current specifications:
|Measurement from throat (inches)||Minimum distance between narrowest point of head|
|1.25||3.0 (All measurements)|
|3.0||3.0 (All measurements)|
|5.0||3.5 to 4 on front; 3.5 on back|
|Widest point||6 to 6.5 on front; 6 on back|
From the 1.25-inch measurement to the top of the crosse, the distance between the sidewalls of the crosse must be at least 3 inches.
Most modern sticks have a tubular metal shaft, usually made of aluminum, titanium or alloys while the head is made of hard plastic. Metal shafts must have a plastic or rubber cap at the end. The heads are strung with string, leather, and mesh. The strings in the pocket are called shooting, accuracy, or "v" strings.
The sport's growth has been hindered by the cost of a player's equipment—a uniform, helmet, shoulder pads, hand protection, and lacrosse sticks. Many players have at least two lacrosse sticks prepared for use in any contest. Traditionally players used sticks made by Native American craftsman. These were expensive and, at times, difficult to find. The introduction of the plastic heads in the 1970s gave players an alternative to the wooden stick, and their mass production has led to greater accessibility and expansion of the sport.
The goalkeeper's responsibility is to prevent the opposition from scoring by directly defending the 6 feet (1.8 m) wide by 6 feet (1.8 m) tall goal. A goalkeeper needs to stop shots that are capable of reaching over 100 miles per hour (160 km/h), and is responsible for directing the team's defense.
Goalkeepers have special privileges when they are in the crease, a circular area surrounding each goal with a radius of 9 feet (2.7 m). Offensive players may not play the ball or make contact with the goalkeeper while he is in the crease. Once a goalkeeper leaves the crease, he loses these privileges.
A goalkeeper's equipment differs from other players'. Instead of shoulder pads and elbow pads, the goalkeeper wears a chest protector. He also wears special "goalie gloves" that have extra padding on the thumb to protect from shots. The head of a goalkeeper's crosse may measure up to 15 inches (38 cm) wide, significantly larger than field players'.
A defensemen is a player position whose responsibility is to assist the goalkeeper in preventing the opposing team from scoring. Each team fields three defensemen. These players generally remain on the defensive half of the field. Unless the defensemen gets the ball and chooses to run up the field and try to score or pass, by doing this they will need to cross the midfield line and signal one midfielder to stay back. A defensemen carries a long crosse which provides an advantage in reach for intercepting passes and checking.
Tactics used by a defensemen include body positioning and checking. Checking means attempting to dispossess the opposition of the ball through body or stick contact. A check may include a "poke check", where a defensemen thrusts his crosse at the top hand or crosse of the opponent in possession of the ball (similar to a billiards shot), or a "slap check", where a player applies a short, two-handed slap to the hand or crosse of the opponent in possession of the ball. A "body check" is allowed as long as the ball is in possession or a loose ball is within five yards of the opposing player and the contact is made to the front or side of the torso of the opposing player. There are also many other checks including the Rusty Gate or Kayak Check which take much more skill and practice to master.
Midfielders contribute offensively and defensively and may roam the entire playing area. Each team fields three midfielders at a time. One midfielder per team may use a long crosse, and in this case is referred to as a "long-stick midfielder." Long-stick midfielders are normally used for defensive possessions and face-offs but can participate in offense as long as he is not subbed off.
Over time, the midfield position has developed into a position of specialties. During play, teams may substitute players in and out freely, a practice known as "on the fly" substitution. The rules state that substitution must occur within the designated exchange area in front of the players' bench. Teams frequently rotate the midfielder specialists off and on the field depending on the ball possession. Some teams have a designated face-off midfielder, referred to as a "fogo" midfielder (an acronym for "face-off and get-off"), who takes the majority of face-offs and is quickly substituted after the face-off. Some teams also designate midfielders as "offensive midfielders" or "defensive midfielders" depending on their strengths and weaknesses.
Each team fields three attackmen at a time, and these players generally remain on the offensive half of the field.
Duration and tie-breaking methods 
Duration of games depends upon the level of play. In international competition, college lacrosse, and Major League Lacrosse, the total playing time is sixty minutes, composed of four fifteen-minute quarters. High school games typically consist of four twelve-minute quarters, while youth leagues may have shorter games. The clock typically stops during all dead ball situations such as between goals or if the ball goes out of bounds. The method of breaking a tie generally consists of an overtime period of 5 minutes in which the first team to score a goal is awarded a sudden victory. International lacrosse plays two five-minute overtime periods, and then applies the sudden victory rule if the score is still tied.
Ball movement and out of play 
Teams must advance the ball or be subjected to loss of possession. Once a team gains possession of the ball in their defensive area, they must move the ball over the midfield line within 20 seconds. If the goalkeeper has possession of the ball in the crease he must pass the ball or vacate the area within four seconds. Failure by the goalkeeper to leave the crease will result in the opposite team being given possession just outside the restraining box. Once the ball crosses the midfield line, a team has 10 seconds to move the ball into the offensive area designated by the restraining box or forfeit possession to their opponents. The term used to define moving the ball from the defensive to offensive area is to "clear" the ball. Offensive players are responsible for "riding" opponents, in other words attempting to deny the opposition a free "clear" of the ball over the midfield line.
If a ball travels outside of the playing area, play is restarted by possession being awarded to the opponents of the team which last touched the ball, unless the ball goes out of bounds due to a shot or a deflected shot. In that case, possession is awarded to the player that is closest to the ball when it leaves the playing area.
For most fouls, the offending player is sent to the penalty box and his team has to play without him and with one less player for a short amount of time. Penalties are classified as either personal fouls or technical fouls. Personal fouls are of a more serious nature and are generally penalized with a 60 second player suspension. Technical fouls are violations of the rules that are not as serious as personal fouls, and are penalized for 30 seconds or a loss of possession. Occasionally a longer penalty may be assessed for more severe infractions. Any player who is penalized for more than five personal fouls is ejected from the game. The penalized team is said to be playing man down defense while the other team is on the man up, or playing "extra man offense." During a typical game, each team will have three to five extra man offense opportunities.
Personal fouls 
Personal fouls (PF) include slashing, tripping, illegal body checking, cross checking, unsportsmanlike conduct, unnecessary roughness, and equipment violations. While a stick-check (where a player makes contact with the opposition player's stick in order to knock the ball loose) is legal, a slashing violation is called when a player viciously makes contact with an opposing player or his stick. An illegal body check penalty is called for any contact where the ball is further than 5 yards (4.6 m) from the contact, the check is from behind, above the shoulders or below the knees, or was avoidable after the player has released the ball. Cross checking, where a player uses the shaft of his stick to push the opposition player off balance, is illegal in field lacrosse. Both unsportsmanlike conduct and unnecessary roughness are subject to the officiating crew's discretion, while equipment violations are governed strictly by regulations.
Technical fouls 
Technical fouls include holding, interference, pushing, screening, "warding off", stalling, and off-sides. A screen, as employed in basketball strategy, is a blocking move by an offensive player, by standing beside or behind a defender, to free a teammate to shoot, or receive a pass. Warding off occurs when an offensive player uses his free hand to control the stick of an opposing player.
Offside has a unique implementation in field lacrosse. Instituted with rule changes in 1921, it limits the number of players that are allowed on either side of the midfield line. Offside occurs when there are fewer than three players on the offensive side of the midfield line or when there are fewer than four players on the defensive half of the midfield line (note: if players are exiting through the special-substitution area, it is not to be determined an offside violation).
A technical foul requires that the defenseman who fouled a player on the opposing team be placed in the penalty box for 30 seconds. As with a personal foul, until the penalty time expires, no replacement for the player is allowed and the team must play one man short. The player (or a replacement) is allowed to reenter the game once the time in the penalty box is over and the team is thus once again at full strength.
Domestic competition 
College lacrosse, a spring sport in the United States, saw its earliest program established by New York University in 1877. The first intercollegiate tournament was held in 1881 featuring four teams: New York University, Princeton University, Columbia University, and Harvard University. This tournament was won by Harvard. The United States Intercollegiate Lacrosse Association (USILA) was created in 1885, and awarded the inaugural Wingate Memorial Trophy to the University of Maryland as national champions in 1936. The award was presented to the team (or teams) with the best record until the National Collegiate Athletic Association (NCAA) instituted a playoff system in 1971. The NCAA sponsored its premier Men's Lacrosse Championship with the 1971 tournament where Cornell University defeated University of Maryland in the final. In addition to the three divisions in the NCAA, college lacrosse in the United States is played by non-varsity Men's Collegiate Lacrosse Association and National College Lacrosse League club teams.
Lacrosse was first witnessed in England, Scotland, Ireland and France in 1867 when a team of Native Americans and Canadians traveled to Europe to showcase the sport. The year after, the English Lacrosse Association was established. In 1876, Queen Victoria attended an exhibition game and was impressed, saying, "The game is very pretty to watch." Throughout Europe, lacrosse is played by numerous club teams and is overseen by the European Lacrosse Federation. Lacrosse was brought to Australia in 1876. The country sponsors various competitions among its states and territories that culminate in the annual Senior Lacrosse Championship tournament.
In 1985, the Canadian University Field Lacrosse Association (CUFLA) was established, with twelve universities in the Ontario and Quebec provinces competing in the intercollegiate league. The league plays its season during the autumn. Unlike the NCAA, the CUFLA allows players that are professional box lacrosse players in the National Lacrosse League to participate, stating that "although stick skills are identical, the game play and rules are different".
Professional field lacrosse made its first appearance in 1988 with the formation of the American Lacrosse League, which folded after five weeks of play. In 2001, professional field lacrosse resurfaced with the inception of Major League Lacrosse (MLL), whose teams, based in the United States and Canada, play during the summer. The MLL modified its rules from the established field lacrosse rules of international, college, and high school programs. To increase scoring, the league employed a sixty second shot clock, a two point goal for shots taken outside a designated perimeter, and reduced the number of long sticks to three rather than the traditional four. Prior to the 2009 MLL season, after eight seasons, the league conformed to traditional field lacrosse rules and allowed a fourth long crosse. The MLL has been bolstered by a ten year television contract with ESPN in 2007.
International competition 
The Federation of International Lacrosse (FIL) is the international governing body of lacrosse and it oversees field, women's and box lacrosse competitions. In 2008, the International Lacrosse Federation and the International Federation of Women's Lacrosse Associations merged to form the FIL. The former International Lacrosse Federation was founded in 1974 to promote and develop the game of men's lacrosse throughout the world. The FIL now sponsors the World Lacrosse Championship and Under-19 World Lacrosse Championships which are played under field lacrosse rules. It also oversees the World Indoor Lacrosse Championship played under box lacrosse rules, and the Women's Lacrosse World Cup and an under-19 championship under women's lacrosse rules.
Lacrosse at the Olympics was a medal earning sport in the 1904 Summer Olympics and the 1908 Summer Olympics. In 1904, three teams competed in the games held in Saint Louis, Missouri. Two Canadian teams, the Winnipeg Shamrocks and a team of Mohawk Indians from the Iroquois Confederacy, and an American team represented by the local St. Louis A.A.A. lacrosse club participated, and the Winnipeg Shamrocks captured the gold medal. The 1908 games held in London, England featured only two teams, representing Canada and Great Britain. The Canadians again won the gold medal in a single championship match by a score of 14–10.
In the 1928 Summer Olympics, 1932 Summer Olympics, and the 1948 Summer Olympics, lacrosse was a demonstration sport. The 1928 Olympics featured three teams: the United States, Canada, and Great Britain. The 1932 games featured a three game exhibition between a Canadian All-star team and the United States. The United States was represented by Johns Hopkins Blue Jays lacrosse in both the 1928 and 1932 Olympics. In order to qualify, the Blue Jays won tournaments in the Olympic years to represent the United States. The 1948 games featured an exhibition by an "All-England" team organized by the English Lacrosse Union and the collegiate lacrosse team from Rensselaer Polytechnic Institute representing the United States. This exhibition ended in a 5–5 tie.
There are obstacles to reestablishing lacrosse as an Olympic sport. One hurdle was resolved in 2008, when the international governing bodies for men's and women's lacrosse merged to form Federation of International Lacrosse. Another obstacle is insufficient international participation. In order to be considered as an Olympic sport the game must be played on four continents, and with at least a total of 75 countries participating. According to one US Lacrosse representative in 2004, "it’ll take 15-20 years for us to get there." For the 1996 Summer Olympics in Atlanta, Georgia and 2000 Summer Olympics in Sydney, Australia, efforts were made to include lacrosse as an exhibition sport, but these failed.
World Lacrosse Championships 
The World Lacrosse Championship began as a four-team invitational tournament in 1967 sanctioned by the International Lacrosse Federation. The 2006 World Lacrosse Championship featured a record twenty-one competing nations. The 2010 World Lacrosse Championship took place in Manchester, England. Only United States, Canada, and Australia have finished in the top two places of this tournament. Since 1990, the Iroquois Nationals, a team consisting of the Six Nations of the Iroquois Confederacy members, have competed in international competition. This team is the only Native American team sanctioned to compete in any men's sport internationally. The Federation of International Lacrosse also sanctions the Under-19 World Lacrosse Championships. The 2008 Under-19 World Lacrosse Championships included twelve countries, with three first-time participants: Bermuda, Finland, and Scotland.
Other regional international competitions are played including the European Lacrosse Championships, sponsored by the twenty-one member European Lacrosse Federation, and the eight team Asian Pacific Lacrosse Tournament.
Attendance records 
Lacrosse attendance has grown with the sport's popularity. The 2008 NCAA Division I Men's Lacrosse Championship was won by Syracuse University, beating Johns Hopkins University 13–10, in front of a title game record crowd of 48,970 fans at Gillette Stadium. The 2007 NCAA Division I Men's Lacrosse Championship weekend held at M&T Bank Stadium in Baltimore, Maryland was played in front of a total crowd of 123,225 fans for the three-day event. The current attendance record for a regular season lacrosse-only event was set by the 2009 Big City Classic, a triple-header at Giants Stadium which drew 22,308 spectators. The Denver Outlaws hold the professional field lacrosse single-game attendance record by playing July 4, 2010 in front of 23,443 fans.
At the 1932 Olympics in Los Angeles, California, over 145,000 spectators watched the three game series between the United States and Canada, including 75,000 people who witnessed the first game of the series while in attendance to watch the final of the marathon.
