The only other big name out for the game on Buffalo's side is defensive tackle Spencer Johnson. Safety Jairus Byrd is listed as questionable (hip) but he did practice on Friday. Wideout Donald Jones and tight end Scott Chandler are both probable.
Other inactives for the Bills: RB Johnny White, QB Tarvaris Jackson, S Delano Howell, LB Kirk Morrison
Two defensive starters for the 49ers were questionable going into the game, but it turns out cornerback Carlos Rogers (ankle) and defensive tackle Isaac Sopoaga (ankle/knee) will both suit up.
