Justin Carl Blackmon (born January 9, 1990) is an American footballwide receiver for the Jacksonville Jaguars of the National Football League (NFL). He played college football at Oklahoma State, where he was twice recognized as a consensus All-American. He was drafted by the Jaguars fifth overall in the 2012 NFL Draft. After playing a full rookie season with the Jaguars, he was suspended twice during 2013 for violations of the NFL's substance abuse policy. He is currently under indefinite suspension for his latest violations, and the Jaguars have said publicly that they are currently awaiting more information on if/when Blackmon will apply for reinstatement. It is unlikely he will be playing for the Jaguars in 2015. 
Blackmon was born in Oceanside, California. He attended Plainview High School in Ardmore, Oklahoma, where he was a four-sport star in football, basketball, baseball and track. In football, he earned SuperPrep All-America honors as a senior after receiving 61 passes for 1,547 yards with 14 touchdowns, rushing for 152 rushing yards with two scores and returning four interceptions for touchdowns, leading his team to a 12-1 mark. In basketball, he was the conference MVP as a junior.
Blackmon also lettered once in track & field. At the 2008 Oklahoma State T&F Championships, he captured the state title in the long jump with a leap of 7.01 meters (22 ft, 10 in), while also placing second in the high jump event, with a leap of 1.98 meters (6 ft, 6 in). After spending the summer working on his 400-meter dash technique, he was challenged by his coach to run under 50 seconds, and he was clocked at 49.2.
Blackmon received an athletic scholarship to attend Oklahoma State University, where he played for coach Mike Gundy's Oklahoma State Cowboys football team from 2008 to 2011. He was redshirted as a true freshman in 2008, but quickly earned a starting position in 2009. He was named the 2010 Big 12 Offensive Player of the Year, the first receiver to earn the honor. He was awarded the Fred Biletnikoff Award as the nation's top receiver, and was recognized as a consensus first-team All-American. Blackmon also holds the NCAA records for most consecutive games gaining 100 yards or more and most games gaining 200 yards or more. Statistically, Blackmon caught 111 passes for 1,782 yards and 20 touchdowns in 12 games during the 2010 season and also added a pair of scores with a 69-yard run and a blocked punt return. This performance earned him the 15th-best season in NCAA history.
Blackmon in 2011
Blackmon finished the 2011 regular season with 121 catches for 1,522 yards and 18 touchdowns. He led the Big 12 in receiving and ranked second nationally in both receptions per game and total receptions. His 15 touchdown catches led the league and represented the third-highest total in the nation. Following his 2010 sophomore season, he was recognized as a unanimous first-team All-American. Despite the extreme defensive game plans geared specifically at stopping him, he emerged as the Biletnikoff Award winner as the nation's top receiver for the second consecutive season; former Texas Tech receiver Michael Crabtree is the only other player to win the Biletnikoff Award twice.
Blackmon announced at the 2012 Fiesta Bowl that he would declare for the NFL draft that year. He caught 8 passes for 186 yards and 3 touchdowns in the game. He was also named the 2012 Fiesta Bowl offensive MVP.
Blackmon decided not to participate in any workouts at the NFL Combine, but he managed to erase questions about his long speed at the Oklahoma State Pro Day. He was considered the best wide receiver in the 2012 NFL Draft, and was predicted to go early in the first round. He has been compared to Anquan Boldin and Terrell Owens. He was drafted by the Jacksonville Jaguars with the fifth pick in the first round of the draft. Jacksonville traded up with the Tampa Bay Buccaneers to draft him, exchanging their number seven selection and a fourth round pick for Tampa Bay's spot. Blackmon was the highest selected Oklahoma State Cowboy since Barry Sanders in 1989.
Blackmon scored his first career touchdown on November 4, 2012 against the Detroit Lions. On November 18, in a game against the Houston Texans, Blackmon had seven receptions for 236 yards. The 236 yards were third-most for an NFL rookie, the most since Jerry Rice as well as the second-most in a game in franchise history, trailing only 291 yards by Jimmy Smith in a September 2000 game at the Baltimore Ravens. Blackmon also combined with Andre Johnson (273 yards on 14 receptions) to have the most receiving yards in a game by two players on different teams. Blackmon finished his 2012 season with 64 receptions and 865 yards receiving, both of which led all NFL rookies. Blackmon also led all rookie receivers in first downs. His 81-yard touchdown reception against Houston was the longest pass completion to any rookie.
On April 20, 2013, Blackmon received a four-game suspension by the NFL for violating the league's Policy and Program for Substances of Abuse. In July, he underwent groin surgery. The Jaguars placed him on the PUP list in which he missed training camp and the start of the preseason. Blackmon returned to the active roster and practiced on August 12, however he missed the first four games of the regular season due to his suspension. In his first game back, he caught 5 passes for 136 yards and a touchdown. In his next game, against the Denver Broncos, he recorded 14 catches for 190 yards.
On November 1, during the Jaguars' bye week, he was suspended indefinitely without pay for again violating the NFL's Policy and Program for Substances of Abuse. He would have been eligible to apply for reinstatement prior to the 2014 season.
However, on May 2, 2014, Jaguars general manager David Caldwell announced that it was unlikely that Blackmon would join the team for the 2014 season. Blackmon was arrested following a traffic stop on July 23, 2014 in Edmond, Oklahoma for possession of marijuana.
On October 1, 2014, Jaguars coach Gus Bradley said Blackmon had voluntarily checked into a 90-day program at an undisclosed location. He also said Blackmon had completed nearly half of his commitment, was doing very well and learning a lot.
