It appears Bills rookie Chris Hairston will be manning the left tackle position - opposite Dallas sackmaster DeMarcus Ware - in Sunday's game in Dallas.
Hairston missed the Washington game with a sprained ankle and dressed but did not play against the Jets on Sunday. But Hairston is confident he's healthy to play this week. If he makes it through practice OK this week, it's expected he will start and Andy Levitre will slide back inside to right guard.
"I think we have to evaluate how well Chris Hairston is," coach Chan Gailey said. "If we can evaluate how well he is, then it gives us an idea of what we can do differently. If he's not well enough, then it's status quo the way we've played the last two weeks."
Meanwhile, Gailey said defensive tackle Kyle Williams was having surgery today to repair the bone spur problem near his ankle that ended his season.
