2024–2025: Two positive clostebol tests, initial finding of no fault followed by WADA agreement for three-month suspension

Civil / administrative proceedings

Sinner tested positive twice for very low concentrations of clostebol in March 2024. An independent tribunal accepted the explanation of accidental contamination through his physiotherapist and found no personal fault or negligence, with forfeiture of Indian Wells points and prize money. WADA appealed and subsequently reached a case resolution agreement in February 2025: Sinner accepted a three-month period of ineligibility.
