Interesting to see how this pans out.
Obviously, for his own sake, you don't want it to be a serious issue, but if he had to be taken out on a wheel chair and doesn't end up going through any protocols it would look pretty suspect. Holding his head, blinking and shyt and not wanting any direct light after the incident indicates he did have a concussion, either that, or he's faking the hell out of it (which I hope isn't the case).
