With Pittsburgh trailing 22-14, Steelers rookie running back Le'Veon Bell lost his helmet diving in for an apparent touchdown from the Baltimore 1-yard line. The touchdown was overturned upon review because Bell's helmet popped off at the half-yard line.
Bell's helmet slammed to the turf, and he quickly left for the locker room to be examined for a potential concussion. The Steelers scored the touchdown, but lost the game to their rivals.
Pittsburgh's margin for error this season has been erased at 5-7. The health of their rookie starting running back will be something to watch in the coming week.
