I believe they mentioned that they operated on Delonte's wrist. This is usually only done if there is a lot of displacement; but it may also be part of why they allowed him back so soon, Unfortunately, one of the dangers with surgery is that you get scaring on the tendons and muscles from the surgery itself as the body ties to heals the affected area.
I can say that it hurts like #@%*! if you torque a broken bone in your hand or wrist. I am just surprised that they let him come back when they did. If you are worried about your wrist you may "trip up" in some other way. Not smart in my book. This was before Arroyo and when Rondo was having foot issues. Shows how little they trusted Nate.
Glad people think he will be fine. Hope they are right!
