Sinner tested positive for clostebol twice in March 2024, with news of his failed drug tests being made public in August later that same year. While the International Tennis Integrity Agency initially cleared the World No. 1 of any wrongdoing, the World Anti-Doping Agency challenged this decision, appealing to the Court of Arbitration for Sport.

In January this year, Sinner was handed a three-month ban, after the WADA ruled that he was inadvertently contaminated by a banned substance and “did not intend to cheat”.

Since news of Jannik Sinner’s failed doping tests was made public last year, Nick Kyrgios has been vocal about his dissatisfaction with the alleged lack of transparency surrounding the case.

After the Italian was handed a three-month ban in January by the WADA, Kyrgios took to X to share his opinion about the ruling:

“So wada come out and say it would be a 1-2 year ban. Obviously Sinner’s team have done everything in their power to just go ahead and take a 3 month ban, no titles lost, no prize money lost. Guilty or not? Sad day for tennis. Fairness in tennis does not exist.”
