ORCHARD PARK, N.Y. (AP) Buffalo Bills defensive tackle Kyle Williams and linebacker Nigel Bradham are both doubtful for Sunday's game against Detroit.
Williams, a three-time Pro Bowl selection, hurt his right knee and Bradham his left knee in a loss at Houston last weekend.
Both players were limited in practice Friday. Williams rode a stationary bike and did individual work after not practicing Wednesday or Thursday.
Starting left guard Chris Williams (back) and wide receiver Marcus Easley (knee) didn't participate in practice and are listed as out for Sunday. Both players were injured Sept. 21 in Buffalo's 22-10 loss to San Diego.
Buffalo (2-2) signed wide receiver Naaman Roosevelt to the practice squad Friday and placed wide receiver Caleb Holley on the practice squad/injured list. Roosevelt played 16 games for the Bills from 2010 to 2011.
