In August 2024 the International Tennis Integrity Agency (ITIA) announced that Jannik Sinner’s blood samples from March that year had twice tested positive for clostebol, an anabolic steroid. He claimed inadvertent exposure by a fitness staff member, which the ITIA accepted. Later in 2024 the World Anti-Doping Agency (WADA) announced that it had filed an appeal of the ITIA’s ruling in the Court of Arbitration for Sport and would seek a one- to two-year ban for Sinner. In February 2025 Sinner and WADA reached a settlement. He accepted a three-month suspension from competition, and WADA affirmed that “Mr. Sinner did not intend to cheat, and…his exposure to clostebol did not provide any performance-enhancing benefit and took place without his knowledge.”
