I'll say again that ankle dislocations look a lot more grotesque and serious than they actually are. They can be popped back in place in a minute (as they did with Hayward in the locker room).
The break is more serious. They haven't said much about it, except the bone had to be displaced for them to have surgery. The ligaments are OK, so it doesn't look too bad. But Hayward is a basketball player, and it will take a lot longer to get into basketball shape than just walking.
I know the situation since I've had the ankle dislocation and my wife had the break. In the latter case, bone displacement was minor enough so the Doc decided not to operate. The healing worked out fine. In Gordon's case, there apparently was enough displacement so that operating was necessary. I think the 6 month estimate is probably pretty good, and he could make it back for the playoffs.
