Danny Cipriani in Union suffered a compound fracture/dislocation to his right ankle a few years ago, I'm not sure if it was as serious because I'm not a doctor (it looked exactly the same and his ankle was basically off and turned the other way. He was injured in May and was back for October.
So if the injury is the same there is chance you can recover, lets hope for Yow Yeh's sake it's not as serious as we're all thinking and he can return to good health, if not his league career
In Yow Yeh's case I notice one of the players puts his head back and makes him lie down so he can't see his injury, who was that? He deserves a pat on the back for his good thinking.
