Sun might have to part with Aussie coach

Sun Yang and his Australian coach could be forced to part ways.

China's swimming prodigy Sun, who bagged two gold medals, in 400m and 1,500m freestyle at the London Olympics, has been pushed to the verge of a split with his mentor, Australian Dennis Cotterell, after Australia swimming's governing body banned Cotterell from coaching foreign swimmers.

Sun confirmed Cotterell's potential departure, but stressed both wanted to continue working together.
