ORCHARD PARK, N.Y. -- Bills rookie cornerback Aaron Williams is out indefinitely after being wheeled off the field on a stretcher with a chest injury against New England on Sunday.
Coach Chan Gailey would only say following Buffalo's come-from-behind 34-31 win that Williams was having tests and it's unlikely the injury is season-ending.
Buffalo's second-round pick, Williams was hurt while making a diving attempt to tackle receiver Wes Welker, who made a catch on a crossing route over the middle with 2:37 left in the third quarter.
Williams landed chest down on the turf, and it also appeared that Bills cornerback Leodis McKelvin might have landed on him.
Williams lay on the field for about five minutes before he was lifted onto a stretcher and taken to the locker room.
The injury further depletes Buffalo's thin defensive secondary, which is already missing veteran Terrence McGee, who's expected to miss a few more weeks with a hamstring injury.
