Eh. I wouldn't say he "collapsed". He was walking off the field and went down probably to avoid his team having to call a timeout or get a delay of game penalty. He looked pretty under control to me. Also, "obviously concussed" is a severe overstatement. You don't have the ability to diagnose a concussion on TV, and you can be woozy without getting a concussion. He was likely seeing stars, but you can't determine if he had a concussion based on watching a play on TV. Is seeing stars and. It being concussed a thing?
