I don't think this is a big deal and here is why. First, it doesn't matter where he gets his surgery, all surgeons are going to be pretty competent, by and large. Maybe he had a family member who knew a great surgeon whom they trusted very much; a doctor-patient relationship is important. Second, having an ACL tear surgery is tough business. It's hard work recovering and in the immediate aftermath of the surgery, getting around is tough. Maybe he's closer to home where family can take care of him and mom can make him some home cooking while he recovers. We don't know the full extent of his injuries, but say he had a meniscus repair, he would have to be off of his feet for a certain time period. Being in dorms makes that very, very difficult. It makes sense to try and recover at home in the short term, and not in a dorm where you have to go down a long hallway just to use the bathroom.
The sky is not falling. There are plenty of reasons that, should this rumor even be true, would not be cause for any concern.
