Chris Kelsay did not practice on Friday.
The defensive end injured his neck Thursday and is questionable to play against Tom Brady and the high powered New England Patriots offense this weekend.
Twice a season since 2001 the Bills have had to deal with Brady. The Patriots quarterback has had a lot of success against the Bills and the rest of the league since stepping in for Drew Bledsoe.
Brady is 19-2 against the Bills and once again this year he's near the top of the league in passing. Back in September against the Bills, Brady had 340 yards passing with three touchdowns and he ran for a touchdown.
"He is the best that I have played," said Bills defensive tackle, Kyle Williams. "I think that it is just on the command that he has on their offense. He knows what the defense you are in and what it might give up, what it might not give up and he puts them in a good position."
"He is one of the elite quarterbacks in the league," said Bills defensive end, Mario Williams. "Ever since he has had his shot, he has always ran with it and done well. He is definitely up there. One of the top quarterbacks in the league still."
