Doping: 8-year stop for Chinese Olympian Sun Yang

Tough anti-doping sanction on Sun Yang, a Chinese swimming icon.
The Olympian was disqualified for eight years by the Arbitral Tribunal of Sport (Tas) for destroying the test tube of a surprise check with a hammer in September 2018.
Sun Yang, 28, now has only one chance to appeal to the Swiss federal court to hope to participate in Tokyo 2020. (ANSA-AFP).
