I'm with you. They showed him for a couple of minutes right after the hit and his legs didn't move at all, and when they cut back again it appeared they still hadn't changed position. He looked like he was conscious even after he hit the ground but after he rolled over he was motionless form then on.
There's no way they call a medi vac if he never lost consciousness and was moving. No way he stays in the hospital over night.
The risk mgmt. guys over at Disney probably have a zero doubt policy especially when dealing with HS athletes. He probably was told to stay down and pre determined plans were put into action. The second/third concussion is the main issue and one that probably will end this young man's fb career.
