The Buffalo Bills were without their two starting defensive tackles in practice on Tuesday, but they'll almost certainly have one against the Patriots on Monday night.

Kyle Williams and Marcell Dareus were both absent, though Dareus was out for a "personal thing." As for Williams, it doesn't sound like he'll be playing against the Patriots.

"I don't think there's any chance of it," Rex Ryan said of Williams playing, via Mike Rodak of ESPN.

Williams has missed the past three games due to a knee injury suffered late in the game in Week 6. Ryan didn't give an update on when Williams will return, but being four weeks removed from the injury, it should be relatively soon.
