Running back Marshawn Lynch and linebacker Kawika Mitchell returned to practice Thursday as the Bills prepared to close their season hosting New England this weekend.
Both missed Wednesday's practice - Lynch with a sore shoulder that kept him out of most of the second half of Buffalo's win at Denver last Sunday, and Mitchell with a knee injury.
Meanwhile, Pro Bowl left tackle Jason Peters (knee) and No. 3 receiver Roscoe Parrish (knee) missed practice for a second straight day.
Bills coach Dick Jauron didn't give any indication of the playing status of any of the injured players.
Sunday's game has significant playoff implications for the Patriots, who must win to stay in the postseason hunt. The Bills will be looking to finish .500 for the first time since 2004.
