Bills RB McCoy questionable with hamstring injury
McCoy suffered a hamstring injury against the New York Jets last weekend. He missed practice on Wednesday before being limited the past two days.
Running back Chris Ivory is also questionable with a shoulder injury, though Ivory was a full participant in practice all week.
Quarterback Derek Anderson cleared concussion protocol on Friday. He was injured on Oct. 29 against the New England Patriots. McDermott didn't say if Anderson or Matt Barkley will serve as Buffalo's No. 2 quarterback.
Cornerback Ryan Lewis (concussion) is out.
