The Bills will be without wide receiver and kick returner Roscoe Parrish for the remainder of the season.
Parrish suffered a left ankle injury on Sunday against the Raiders.
He was carted off from the sideline after getting hurt in the second quarter while blocking on teammate Steve Johnson's 19-yard catch.
Parrish missed the second half of the 2010 season with a wrist injury.
