Kyle Williams, who was listed as questionable for last week's win over Arizona, gets that designation again after missing practice on Wednesday and Thursday to rest up an ankle injury. He's joined in that department by Spencer Johnson, who has missed the last two weeks with an ankle injury of his own. Both Williams and Johnson are expected to play on Sunday, giving the Bills a bit more depth on the interior than they've had of late.
Also questionable: cornerback Terrence McGee and safety Da'Norris Searcy. McGee, who is still not fully recovered from off-season knee surgery, was a limited practice participant on Friday, but did not suit up on either of the two preceding days. If he can't play, younger guys like Aaron Williams, Justin Rogers and perhaps especially Leodis McKelvin will see an uptick in playing time. Searcy, dealing with an ankle injury of his own, practiced on a limited basis on each of the last two days, and seems likely to suit up.
Three starters - left tackle Cordy Glenn, right guard Kraig Urbik and defensive end Mark Anderson - have been ruled out. The good news for the offensive linemen is that head coach Chan Gailey expects both players to be on the field when the team takes on the Houston Texans in Week 9, following the Bills' bye week. They'll once again be replaced in the starting lineup by Chris Hairston and Chad Rinehart, respectively. As Anderson sits, Chris Kelsay, Kyle Moore and the newly re-signed Shawne Merriman will get reps in his stead.
Finally, two players were listed as probable: Brad Smith (chest) and Mario Williams (wrist). Both players were full participants on all three days of practice this week, so it's a very safe bet that both will be on the field against Tennessee.
