My only concern is that when he walked off the court and when he came back out to support his team (which I love that he did, what a guy!) he kept the hand concealed, which to me implies that the physical damage that the hand received may be a little more severe than the standard dislocation. Also he came down hard on it. I have a horrible feeling this injury may nag him for a good while, just like the ankle sprain last year.
But until we get more details,we can only hope it is not serious.
