The Buffalo Bills placed offensive lineman Chad Rinehart on injured reserve with an ankle injury and activated cornerback Ron Brooks. Rinehart, a backup who started three consecutive games, was injured during the team's loss to the Tennessee Titans two weeks ago and coach Chan Gailey indicated it would be a long-term injury. Brooks was on injured reserve with the designated for return label each team can use for one player beginning this season. Brooks is a rookie fourth-round pick out of LSU who injured his foot before the start of the season. He'll help the club's depth and special teams and may challenge for more playing time at a position of concern right now.
