Nick Kyrgios trolls Jannik Sinner amid possible two-year ban for doping after WADA appeal
Nick Kyrgios has trolled Jannik Sinner after an appeal from the World Anti-Doping Agency (WADA), with the Italian tennis star once again facing a possible two-year ban. It was thought that Sinner had escaped suspension after being let off the hook by the International Tennis Integrity Agency (ITIA) for two failed drugs tests in March.
