PARIS: The Court of Arbitration for Sport said on Tuesday it was postponing its hearing on the decision by Fina, the governing body of swimming, to clear Chinese star Sun Yang of doping.

Triple Olympic champion Sun Yang was accused of smashing a blood vial with a hammer during an out-of-competition doping test last year, but was in January cleared by Fina.

Fina agreed with Sun that testers had failed to produce adequate identification or follow correct protocol. The World Anti-Doping Agency (Wada) responded by taking the case to CAS.

After escaping a ban, Sun was able to compete in the in the World Championships in Gwangju in July, where he won two golds but became a focus of protests from rivals. – AFP
