Well, the doctors told him that he don`t need a surgey and that threatment and rest is enough to heal, it just takes the time, so why should he not listen to them? They are profis, they know what is to do. The thing is that he did return too early, the wrist wasn`t fully healed yet. He wanted to play again too early. So now there is resting again for some weeks.
The news is that he has to wear a plaster cast, like for broken bones.
