As expected, starting right tackle Cordy Glenn will not play with an ankle injury. He did not practice all week. Starting center Colin Brown is also out for Buffalo, as is starting guard Kraig Urbik.
The Bills announced star defensive end Mario Williams is probable for the game. Given the injuries Arizona has suffered on their offensive line, Williams could be in for a big game. Cornerback Aaron Williams, who has started all five games this season, was limited in practice with a hand injury, but he is also listed as probable for Sunday. Free safety Jairus Byrd, a 16-game starter in 2011, is questionable with a chest issue.
