Cam's Swivel Head

Fans got to see for themselves whether QB Cam Newton got a concussion in the waning moments of the Panthers 21- 20 loss to the Broncos.

Cam was called for intentional grounding, but took a vicious shot to the head. He stayed in the game. Nobody from the training staff examined him, but the slow-motion replay was very clear.

There will be a fine for the hit, but how is Cam's head after that hit?
