Kolar (forearm) is questionable to return to Sunday's game against the Raiders.
Kolar went to the locker room during the second half of Sunday's game after sustaining a forearm injury, and he's being evaluated by medical staff to determine whether he can return. With David Njoku (knee) ruled out for the rest of the game, Oronde Gadsden is the only healthy tight end left on the Chargers' game day roster.
