For another week, the Bills will be without cornerback Stephon Gilmore.

The Bills ruled Gilmore (wrist) out for Sunday's game against the Baltimore Ravens. Gilmore has yet to play a game in the 2013 season.

Safety Jairus Byrd (foot) is questionable, though he hasn't participated in a game in 2013 either. The Bills secondary has suffered as a result, giving up 262.3 yards through the air per game.

Also on the injury report, the Bills are listing C.J. Spiller (quad), defensive end Mario Williams (ankle) and receiver Stevie Johnson (hamstring) as probable.
