Bills quarterback Tyrod Taylor was carted away from the sideline with what the team said was a knee injury early in the fourth quarter against the New England Patriots.

The Bills said Taylor wouldn’t return to the game.

It wasn’t immediately clear when Taylor was hurt, although he came up limping and favoring his right leg after being sacked on the game’s opening play.

He continued until the second half, when he left the field after a possession and headed to the sideline tent where players can be evaluated for injuries. Then he was driven away.

Taylor finished 9 of 18 for 65 yards passing and an interception before giving way to rookie Nathan Peterman.

This was Peterman’s first appearance in a game since throwing five interceptions in the first half of a 54-24 loss to the Los Angeles Chargers on Nov. 19. There had been talk around Buffalo about returning to Peterman, as horribly as he looked, as the Bills did not want to commit to Taylor.
