Australian tennis star Nick Kyrgios has accepted and served a reduced one-month suspension after testing positive for cocaine at an ATP Tour event in Mallorca, Spain, in June, the International Tennis Integrity Agency (ITIA) has confirmed.

Kyrgios 31, had been provisionally suspended since August 4 after the positive test. Under World Anti-Doping Agency (WADA) rules, the violation would ordinarily carry a three-month suspension. However, the ITIA reduced the sanction after Kyrgios agreed to enter an approved treatment programme.

During an interview with ITIA investigators, Kyrgios said the cocaine use occurred socially during a night out before he was due to compete in Mallorca. The ITIA consulted an independent scientific expert at a WADA-accredited laboratory, who determined that his explanation was consistent with the level of cocaine detected in his sample.

Based on that assessment, the ITIA accepted that Kyrgios had used cocaine outside competition. Cocaine remains prohibited in-competition and can trigger a provisional suspension.

Kyrgios's suspension ends on Thursday, subject to completion of the treatment programme. However, he will forfeit the prize money and ranking points earned at the Mallorca event.

The Australian previously apologised for the failed test on social media, describing it as a “huge mistake” and accepting full responsibility.
