Bills defensive tackle Williams questionable vs. Steelers

ORCHARD PARK, N.Y. (AP) Buffalo Bills defensive tackle Kyle Williams is questionable for Sunday's game against the Pittsburgh Steelers because of a back injury.

Bills coach Rex Ryan says Williams' back locked up on him Thursday night, placing his availability for the game in doubt.

Ryan says, ''Obviously that's a big concern.''

Williams has started all 12 games this season, racking up 55 tackles and 3.5 sacks. He missed 10 games last year because of a knee injury.

The Bills will be healthy at wide receiver, one of the few times this season. Receivers Sammy Watkins (foot) and Robert Woods (knee) are expected to play.
