The Bills have placed injured quarterback Kevin Kolb on the season-ending injured reserve list, a league source told WGR 550 AM radio in Buffalo.

Kolb, who signed with the Bills in the offseason, suffered a concussion in the team's third preseason game that could potentially end his career. Undrafted rookie quarterback Jeff Tuel is expected to start Week 1 against the Patriots if EJ Manuel is not ready to return from knee surgery.
