(Reuters) - The Court of Arbitration of Sport (CAS) will announce on Friday whether multiple Chinese swimming champion Sun Yang has been found guilty of a doping offence, it said in a statement on Thursday.
CAS has to decide whether to accept an appeal from the World Anti-Doping Agency (WADA) against a decision by world swimming's ruling body FINA to clear Sun of wrongdoing for his conduct during an out-of-competition test in September 2018.
A public hearing in November heard that Sun questioned the credentials of the testers before members of his entourage smashed the vials containing his blood samples with a hammer.
Sun said the testers failed to show their identity and behaved in an unprofessional manner.
CAS said the decision would be announced at 0900 GMT.
