Former Wimbledon champion Marketa Vondrousova is facing a potential four-year ban from tennis after being charged with refusing a doping test by the International Tennis Integrity Agency (ITIA). The incident occurred in December 2025 when a doping control officer visited her home late at night. Vondrousova has stated she felt frightened and unsafe during the encounter, citing months of physical and mental stress as contributing factors to her reaction.
The Czech player, who won the women’s singles title at Wimbledon in 2023, revealed in an Instagram statement that experts confirmed she had suffered an acute stress reaction and generalized anxiety disorder around the time of the incident. She explained that when someone rang her door late at night without proper identification or adherence to protocol, she reacted as a person who felt scared, emphasizing that her concern was for her safety, not avoiding the test.
According to the ITIA, players are required to log their whereabouts for a specific hour each day to allow for out-of-competition anti-doping tests. Failure to comply with testing procedures can result in sanctions under the Tennis Anti-Doping Protocol (TADP), with a maximum penalty of four years’ suspension for a first offense involving test refusal or evasion.
Vondrousova, currently ranked No. 46 in the women’s rankings, has not played a WTA Tour match since January 2026 due to shoulder pain. She withdrew from the Adelaide International earlier that month and has remained inactive on the professional circuit since. Despite the charge, she is permitted to continue playing while the investigation proceeds, as the offense does not trigger an immediate provisional suspension.
The ITIA has confirmed that an investigation is underway and that Vondrousova has been formally charged with refusing a test. However, the agency has declined to comment further on the specifics of the case, citing the ongoing nature of the proceedings. Both Vondrousova and her legal team, led by lawyer Jan Exner, have expressed confidence that once the full context is reviewed, her name will be cleared.
Her lawyer stated via text message that he and his client are certain the hearing will vindicate her actions, arguing that her response was driven by fear and psychological distress rather than intent to circumvent anti-doping rules. Vondrousova has reiterated that in the moment, fear clouded her judgment and prevented her from processing the situation rationally.
The case highlights ongoing tensions between athlete welfare and the strict enforcement of anti-doping regulations, particularly concerning out-of-competition testing protocols. Mental health advocates have pointed to such incidents as evidence of the need for greater flexibility and understanding when athletes experience acute psychological crises.
As of now, no hearing date has been publicly confirmed. Vondrousova remains eligible to compete unless and until a formal sanction is imposed following the conclusion of the ITIA’s disciplinary process. Updates on the case are expected to be issued by the ITIA upon reaching a decision.
