What I just heard from ESPN was that "no charges" were pending, so you sure you heard that right? Edit: N/M, looked it up, guess I heard it wrong, says charges are pending.
Also, they've been saying he was seriously injured, but they're also saying he's already been released from the hospital, the only thing I can think of that would make them say it was a serious injury yet he's already been released is maybe he broke his arm or a leg, something that would prevent him from playing for awhile.
