Peterman to start for Bills; Anderson out with concussion

BUFFALO, N.Y. (AP) — Nathan Peterman will start at quarterback for the Buffalo Bills on Sunday against the Chicago Bears after Derek Anderson was ruled out with a concussion.

The Bills (2-6) said Saturday that Anderson and rookie linebacker Tremaine Edmunds have not cleared concussion protocol.

Rookie quarterback Josh Allen has a sprained elbow) and already has been ruled out for a third straight game. Anderson was hurt in the final minutes of a 25-6 loss to New England on Monday night.

Buffalo signed journeyman Matt Barkley on Wednesday to back up Peterman.

Peterman was Buffalo's opening-game starter but has been benched twice this season for poor performances. The second-year quarterback has thrown nine interceptions in 81 career attempts.
