Well Lady TT, the old adage of the bigger they are, the harder they fall might be true in Juan's case. But it is a shame.
And Rafa just puts so much effort into everything, it's not surprising either. I might be wrong, but it doesn't surprise me that his right wrist (only used in the two handed backhand) got hurt. From seeing his practices in the past, he doesn't seem to practice a lot with the backhand, even runs around it in practice. So I think being underused, it is more prone to sudden stress when he does use it, and tries to apply a lot of power.
Well, that's my own theory. General Hercules might have a different opinion. I guess it could have just been a freak injury, if he fell or something, but that was not my understanding of what happened. Eh, guess it doesn't matter now. But the physical trainers try to look for reasons and solutions to avoid these things in the future.
Now I just heard his doctors don't know how long he will be out, which seems a bit strange. Because when he first announced it, doctors were hopeful that it would be ok in 2-3 weeks, and he was practicing and looked almost ready to play in the US Open, except for that splint. But I guess when he took it off and tried to use it, it was not good enough. Oh well, next scheduled match is Shanghai in October. If he can't be ready for that, then there is a certainly much more serious problem.
