Wood, dealing with an ankle injury, missed practice all week and will miss his second consecutive start. He'll be replaced in the starting lineup by Kraig Urbik. McGee continues to deal with a nerve problem; he, too, missed practice all week, and despite not being officially ruled out, it's a virtual certainty he will be inactive on Sunday for the seventh time this season. As usual, Leodis McKelvin will start at cornerback.
Shawn Nelson is also out as he continues to battle migraines. The Bills have worked tirelessly to fortify the tight end position this week, adding Mike Caussin and Scott Chandler to the active roster.
Torell Troup, whose fibula injury kept him out of practice on Wednesday and Thursday, was able to participate on Friday. He is listed as questionable; if he can't play, John McCargo may be active for the first time this season.
Chris Kelsay, who has been battling an illness since before the Pittsburgh game, is listed as probable. He's joined there by C.J. Spiller and Spencer Johnson, whose respective hamstring injuries kept them out of Buffalo's last two games. They will be in the lineup on Sunday. Finally, as is the case every week, Demetrius Bell is listed as probable after missing Wednesday's practice due to rest.
