American tennis player Jessica Eudovic has been provisionally suspended under the tennis anti-doping programme (TADP) after testing positive for prohibited substance clostebol. The 18-year-old tested positive for the substance after providing a sample during a W15 tennis event in Santa Tecla, El Salvador, in October.
Eudovic, who climbed to a career-high singles ranking of 1,104 in October, was most recently in competitive action last month when she was defeated in straight sets by compatriot Anastasia Sysoeva in the qualifying rounds of a WTT W35 event in Florida. The teenager has previously represented Saint Lucia in the Billie Jean King Cup.
Announcing Eudovic’s provisional suspension, the International Tennis Integrity Agency (ITIA) revealed it had “sent the player a pre-charge notice of an anti-doping rule violation on 21 November 2025 under article 2.1 of the TADP (presence of a prohibited substance in a player’s sample) and/or article 2.2 (use of a prohibited substance without a valid therapeutic use exemption (TUE)).”
And the ITIA’s statement explained: “The sample was split into A and B samples and the subsequent analysis found that both samples contained a metabolite of clostebol, which is prohibited under the TADP, in the category of anabolic androgenic steroids (section S1.1 of the 2025 world anti-doping agency prohibited list).
“Clostebol is a non-specified substance, and Eudovic did not possess a valid TUE for the substance. Findings for non-specified substances carry a mandatory provisional suspension – in Eudovic’s case, this has been in effect from 21 November 2025.”
The ITIA then stated: “Players have the right to appeal the imposition of their provisional suspension before an independent tribunal chair.
“On 1 December 2025, Eudovic filed an appeal, which was dismissed on 16 December 2025 by independent chair Dr Tanja Haug, who stated that the basis of Eudovic’s appeal was ‘insufficient to meet the threshold required to lift a Provisional Suspension.’”
And the organisation added: “While provisionally suspended, Eudovic is prohibited from playing in, coaching at, or attending any tennis event authorised or sanctioned by the members of the ITIA (ATP, ITF, WTA, Tennis Australia, Federation Francaise de Tennis, Wimbledon and USTA) or any national association.”
The ITIA is an independent body established in 2021 by the ATP, ITF, WTA and Grand Slams, with the organisation aiming to promote, encourage, enhance and safeguard the integrity of their member’s professional tennis events across the world.
According to its website, the organisation helps players, coaches, officials and support staff to understand the rules and avoid breaching them.
