Byrd attended Mustang High School in Mustang, Oklahoma. In his senior year, he was named an All-State defensive end. He enrolled at the University of Tulsa, where he played college football for the Tulsa Golden Hurricane. Byrd started for the Golden Hurricane defense for four seasons, registering 321 tackles and 20 quarterback sacks. College Football News selected Byrd as an All-Americanhonorable mention after his senior season, where he had 108 tackles, 11 sacks, and 35 quarterback hurries. The New York Jets of the National Football League selected Byrd in the second round of the 1989 NFL Draft, with the hope that he could succeed Mark Gastineau. He played for the Jets as a backup defensive end in a 3–4 defense in 1989, registering seven sacks. The Jets switched to a 4–3 defense in 1990, and Byrd became a defensive tackle that season. Byrd made 13 sacks in 1990 and seven sacks in 1991. He again played as a defensive end in 1992. Byrd missed a month of the 1992 season due to a shoulder injury.
Injury and recovery
Byrd suffered a neck injury during an NFL game against the Kansas City Chiefs on November 29, 1992. During the play, he rushed in an attempt to sack Chiefs quarterback Dave Krieg, but Krieg stepped up to avoid the tackle, and Byrd collided with Jets teammate Scott Mersereau. He ducked his head at the last moment before he collided with Mersereau's chest. The head-first collision broke his fifth cervical vertebrae and left him unable to walk. During his recovery, the Jets briefly used an ichthys logo bearing his uniform number, No. 90. After extensive physical therapy, Byrd walked again, but could no longer return to playing football. Byrd returned to the Meadowlands for the Jets' home opener on September 5, 1993, walking to midfield as an honorary captain for the coin toss. During a halftime ceremony, Jets president Steve Gutman presented him with a trophy for the Most Inspirational Player Award, which would thereafter be called the Dennis Byrd Award.
Later life
The Jets retired Byrd's No. 90 during a half-time ceremony on October 28, 2012, against the Miami Dolphins. However, it had been informally retired for some time before then; the Jets had not reissued No. 90 since Byrd's injury. Byrd was the co-author with journalist Michael D'Orso of an autobiographical work titled Rise and Walk: The Trial and Triumph of Dennis Byrd and the subject of a made-for-television film . Peter Berg played him in the movie. Byrd spent several years traveling across the country and sharing his life story. He served as defensive line coach at Owasso High School in Owasso, Oklahoma and later at Lincoln Christian School in Tulsa. He lived outside of Tulsa with his wife, the former Angela Hales, and their four children. He was a devout Pentecostal. During the week leading up to the between the Jets and the Patriots, Byrd sent Jets' head coachRex Ryan his tattered, cut up jersey that had been cut from his body on the day of his injury along with an inspirational letter addressed to the Jets. Ryan was so moved by this that he invited him to come out and personally address the team prior to the Patriots game. The inspired Jets carried his jersey to the coin toss prior to the game; the Jets won 28–21.

Byrd was the third child of five born to Daniel and Nancy Byrd. He was born in Oklahoma City. Dennis and his wife Angela were married Dec. 20, 1986 and had four children.
