Sun Yang of China celebrates after men's 400m freestyle final of swimming at the 18th Asian Games in Jakarta, Indonesia, Aug. 21, 2018. Sun won the gold medal. (Xinhua/Fei Maohua)China's triple Olympic swimming champion Sun Yang on Tuesday described as "intolerable" the speculation surrounding him ahead of a Court of Arbitration for Sport hearing into a murky missed drugs test.The 27-year-old's career is in jeopardy after he was accused of smashing a blood vial with a hammer during an out-of-competition dope test last year.FINA agreed with Sun that testers failed to produce adequate identification or follow protocol, but the World Anti-Doping Agency responded by taking the case to the Lausanne-based CAS."Misguided public opinion has distorted the facts," Sun, a hero to millions in China but derided as a "drugs cheat" by some of his rivals, wrote on social media."My training and my personal life have been greatly disturbed by this and it's become intolerable."Sun, a controversial character, was allowed to compete in the FINA world championships in South Korea in July, winning two golds but also becoming a focus of protests from other swimmers.Writing on Weibo, Sun said that he was looking forward to giving his account of what happened during the now-infamous doping test."There is something I can't say, I can't make the truth public," he added in the post."But fortunately the surveillance cameras have recorded everything, otherwise I won't be able to defend myself against irresponsible accusations."A CAS hearing was originally scheduled for September, but is now unlikely to be before the end of October, CAS said earlier this month.
