Teenage American tennis player handed provisional suspension over failed drugs test

Jessica Eudovic has been provisionally suspended from tennis after testing positive for a banned substance.

The 18-year-old American tested positive for clostebol in a sample she submitted at an ITF World Tour event in El Salvador in October.

A metabolite of clostebol was found in both of her A and B samples during analysis.

Eudovic has now been handed a provisional suspension under the Tennis Anti-Doping Programme [TADP].

In a statement, the International Tennis Integrity Agency [ITIA] said: “The ITIA 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]].”

“Clostebol is a non-Specified substance, and Eudovic did not possess a valid TUE for the substance,” they added.

“Findings for non-Specified Substances carry a mandatory provisional suspension – in Eudovic’s case, this has been in effect from 21 November 2025.

“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.’

“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.”

Eudovic reached a career-high singles ranking of 1,104 on the ITF circuit in October.

She was beaten by Jade Bornay in the second round of qualifying at the event in El Salvador.

What is clostebol?

Clostebol is a prohibited substance as per TADP regulations.

It is categorised as an anabolic androgenic steroid in section S1.1 of the 2025 World Anti-Doping Agency [WADA] Prohibited list.

Four-time men’s singles Grand Slam winner Jannik Sinner was banned for three months earlier this year for two positive tests.

WADA accepted his explanation that the substance was inadvertently delivered by his physiotherapist.

They also said that Sinner ‘did not intend to cheat’, and the clostebol did not provide him with ‘any performance-enhancing benefit’.

Sinner, who reached a settlement with WADA regarding his ban, was ineligible to compete from February 9 to May 4.

He therefore returned in time for the French Open, during which he reached the final, but lost to Carlos Alcaraz.
