he landed on that shoulder really awkward. Looked like it REALLY hurt. But I dont see where he got the concussion, hopefully that's a misdiagnosis.
His head also bounced a weird way when he hit the mat. It's not so much the blunt force trauma that causes a concussion as it is the brain moving around within the skull on the rebound from the initial hit. If you watch the rest of the match, it is obvious that Cody was barely aware of his surroundings. Props to that dude for finishing the match in a professional manner. He definitely has his father's toughness. If it is a minor concussion he will bounce back soon, but the shoulder injury is more detrimental to him.
