Three-time Olympic champion Yang Sun has been banned for eight years for missing a doping test in September 2018. After being cleared by FINA, the World Anti-Doping Agency filed an appeal with the Court of Arbitration for Sport for the decision to be overturned. This case will lead to serious questions about the credibility of FINA. The eight-year ban is a sign that the sport is cracking the whip on doping and attempting to restore faith in the system.
