Kyle Blaine Kosier (/ˈkʃər/; born November 27, 1978) is a former American football guard in the National Football League for the San Francisco 49ers, Detroit Lions and the Dallas Cowboys. He played college football at Arizona State University.

Early years[edit]

Kosier attended Cactus High School in Glendale, Arizona,[1] where he was a letterman in football, basketball, baseball, and track.

In football, his athleticism allowed him to play middle linebacker at a bigger size than most players could. As a senior in 1996, the Arizona Republic named him to the All-Arizona Team, and KPNX-TV named him the 1996 Arizona Class 4A Defensive Player of the Year. He finished with 634 career tackles.

In 2011, he became the first football player to have his jersey retired by Cactus High School.

College career[edit]

Kosier accepted a scholarship from Arizona State University to play defensive end, but a shortage of offensive linemen made him convert to offensive guard as a redshirt freshman. The next year he started the last 2 games of the season at right guard.

He was a starter at right guard as a junior and at right tackle as a senior, receiving honorable-mention All-Pac-10 honors.[2]

Professional career[edit]

San Francisco 49ers[edit]

Kosier was selected by the San Francisco 49ers in seventh round (248th overall) of the 2002 NFL Draft. He played mostly on special teams as a rookie. The next year he became a starter at both left guard and right tackle.

In 2003, he started 7 games at left guard, 3 at right guard and 2 at right tackle. The next year he started 16 games rotating between left tackle (10 games) and right guard (6 games).

Detroit Lions[edit]

On April 19, 2005, the Detroit Lions signed him as a restricted free agent to a one-year contract, reuniting with his former 49ers head coach Steve Mariucci. The 49ers did not match the offer and received a seventh-round draft choice (#223-Marcus Maxwell) from the Lions as compensation.

Kosier was initially used by the team as a swing tackle, until being named the starting left guard for the last 11 games.

Dallas Cowboys[edit]

On March 11, 2003, he was signed as an unrestricted free agent by the Dallas Cowboys. Although the move was made to replace Larry Allen at left guard, it didn't get much acknowledgment because Kosier was a relatively unknown player. He started 80 games over six seasons, missing 13 games in 2008 with a hairline fracture in his right foot and 3 with knee/ankle injuries in 2010.

During the 2011 season, he was moved to right guard to help with the development of rookie right tackle Tyron Smith, who became a Pro Bowl alternate. Kosier played that year with a plantar fascia injury, before suffering a torn ligament in his left knee in the last game of the regular season.

Throughout his Cowboys years, he always remained an important presence in the locker room, often getting recognition for the versatility, chemistry and stability he provided to the offensive line. On March 19, 2012, he was released after becoming expendable with the signings of free agent offensive guards Mackenzy Bernadeau and Nate Livings.[3]

Personal life[edit]

Kosier was born in Peoria, Arizona. Kosier is Jewish,[4] as is his mother.[5] On discovering that Dallas Cowboys teammate Igor Olshansky was also Jewish, he said: "That's kind of cool to have a teammate share the same faith that I have".[6]
