MELBOURNE (Reuters) - Sun Yang's coach Denis Cotterell has cut ties with the Chinese Olympic champion following the swimmer's eight-year ban for doping, Australian media reported on Sunday.

Cotterell told News Ltd media he would not back Sun's appeal to the Swiss federal court as he sought to overturn the decision by the Court of Arbitration (CAS) for Sport last week.
