The Buffalo Bills have placed linebacker Angelo Crowell on injured reserve after he underwent arthroscopic knee surgery Thursday, meaning he will miss the entire 2008 season.

The teams starting strong-side linebacker had been bothered by swelling in his knee throughout training camp, but had worked out with the team all week before having the surgery Thursday. Keith Ellison wil replace Crowell in the lineup this season, starting Sunday against Seattle.
