Colvin, 30, played outside linebacker for the Patriots the past five seasons. He is expected to play a role as a pass-rush specialist for the Texans opposite former first round pick Mario Williams. Colvin has experience as a pass rusher, a role he played for the Chicago Bears early in his career.
Colvin played in 11 games for the Patriots in 2007, ending his season early due to a serious foot injury. He managed 27 tackles (17 solo) with four sacks, 2 passes defended and one interception. Arguably his best season in New England was 2006 when he recorded 53 tackles (42 solo), with 8.5 sacks and three passes defended.
Colvin was released by New England on February 26 after failing a physical. By releasing the Purdue product, the team saved approximately $5.8 million of his $7.4 million cap charge for 2008.
Colvin drew interest from other AFC contenders before agreeing to terms with the Texans. He visited the Indianapolis Colts and received interest from other teams including the Cleveland Browns and the New York Jets. Colvin visited Houston the first week of June where he passed a physical for the team.
