Bills' Terrel Bernard: Ruled out with concussion

Bernard (concussion) won't return to Sunday's game against the Bengals.

Bernard was evaluated for a head injury in the first half, and he was downgraded to out at halftime. With the starting middle linebacker sidelined, Tyler Matakevich could see more snaps in a banged-up Buffalo linebacker corps that's already operating without Baylon Spector (hamstring), A.J. Klein (back) and Matt Milano (leg).
