ORCHARD PARK, N.Y. (AP) - Pro Bowl left tackle Jason Peters is doubtful for the Buffalo Bills' game against New England after missing his third straight practice on Friday because of a knee injury.

Peters will likely miss his second straight game Sunday after not playing in Buffalo's win at Denver last week.

Receiver/punt returner Roscoe Parrish is also doubtful after missing practice all week because of a knee injury. Parrish was hurt last Friday in practice and aggravated the injury against the Broncos.

Running back Marshawn Lynch (shoulder) and linebacker Kawika Mitchell (knee) are both questionable. Starting cornerback Jabari Greer will miss his sixth straight game because of a knee injury.

The Patriots (10-5) need to win to preserve their postseason chances, while the Bills (7-8) can finish at .500 for the first time since 2004.
