Just days away from his return to tennis at the Brisbane International, Nick Kyrgios hasn’t minced his words in referring to doping-related charges against Jannik Sinner and Iga Swiatek, labelling breaches of the sport’s anti-doping program as “disgusting for our sport.”

The International Tennis Integrity Agency (ITIA) levelled charges against World No. 1 Sinner and former World No.1 Iga Swiatek. Sinner tested positive twice for an anabolic steroid in March, but avoided a ban because the ITIA determined he was not to blame.
