China's world and Olympic swimming champion Sun Yang served a three-month ban earlier this year after testing positive for a banned stimulant, the China Anti-Doping Agency (CHINADA) said on Monday.
The World Anti-Doping Agency (WADA) will review the reasons behind the three-month ban handed to Chinese Olympic swimming champion Sun Yang and decide whether to appeal the decision to the Court of Arbitration for Sport (CAS).
Olympic swimming gold medallist Park Tae-hwan has been left "shocked" by a positive doping test, which his agency has attributed to an injection given to the South Korean swim star during chiropractic treatment ahead of last year's Asian Games.
