What was the Jannik Sinner doping controversy?
Jannik Sinner was involved in a doping controversy in 2024, which ended in early 2025, after twice testing positive for clostebol, a banned anabolic steroid.
The positive tests occurred in March 2024 during Indian Wells and an out-of-competition test. Sinner’s defence centred on inadvertent contamination: his physiotherapist, who had a cut finger, used an over-the-counter clostebol-containing spray (Trofodermin) and then massaged Sinner without gloves, transferring the substance.
The International Tennis Integrity Agency (ITIA) initially cleared Sinner of “no fault or negligence.” However, the World Anti-Doping Agency (WADA) appealed, arguing strict liability and seeking a two-year ban. To avoid a lengthy legal battle, Sinner and WADA settled in February 2025.
Sinner accepted a three-month ban, retroactive from February 9 to May 4, 2025. This allowed him to play in the French Open, but he forfeited prize money and ranking points from Indian Wells.
