Sun Yang could be in trouble.

The only swimmer to have ever won Olympic gold medals at 200m, 400m, and 1500m freestyle, now faces a lifetime ban, according to an incredible report from The Times.

In a story that sounds too bizarre to be true, Sun, who was banned in 2014 for doping, is said to have clashed with anti-doping testers in a run-in, where most notably, a sealed blood sample was destroyed by him and one of the Chinese star’s security guards.

Per The Times, after forcing testers to wait outside his house for almost an hour, Sun and his team then challenged whether the officials were legitimate.

Sun then broke a number of testing protocols — including leaving the control room unaccompanied to pass urine — before the swimmer’s mother, according to witnesses, ordered one of the security guards to destroy a vial of blood of Sun’s that was taken at a nearby clubhouse.

Coming to Sun’s support, Dr. Ba Zhen — who also has a previous doping suspension — then reportedly contacted Dr Han Zhaoqi, head of the Zhejiang Anti-Doping Centre.

Dr. Han is also the chief doctor at the hospital he and Dr. Ba work at. The report goes on to detail how Dr. Han, who wasn’t on the scene, told a FINA (Fédération Internationale de Natation) doping panel hearing that the nurse at Sun’s testing didn’t have the necessary paperwork.

Per The Times: “The panel accepted his word, stating in their report that they would “never know” the truth of that. And on January 3 the panel ruled in the swimmer’s favour.”

However, with the deadline nearing for appeals to be lodged at the Court of Arbitration for Sport, WADA has reportedly requested more information on the almost unbelievable events that are said to have transpired.

While FINA green-lit Sun in their hearing, The Times’ reporting suggests WADA are far from satisfied, with a senior source describing the events as “unbelievable and unacceptable.”
