Vondrousova handed four-year ban for refusing anti-doping test
The International Tennis Integrity Agency ruled that stress and fear did not constitute a compelling justification for denying entry to a testing officer at her home in December 2025.

Former Wimbledon champion Marketa Vondrousova has been suspended for four years by the International Tennis Integrity Agency (ITIA) after refusing an anti-doping test at her residence in December 2025. The 26-year-old Czech player, who won the women’s singles title in 2023, was charged after denying a doping control officer entry to her home, an incident that has resulted in a suspension scheduled to end on 21 June 2030.
Vondrousova argued that she feared for her safety when the officer approached her door late at night without properly identifying themselves or following protocol. She cited the 2016 knife attack on fellow Czech player Petra Kvitova as context for her concerns, stating that in that moment, her priority was feeling safe rather than avoiding testing. The ITIA, however, maintained that all officers carry identification and a letter of authority, and players can request a unique ID code as an additional safety measure.
An independent tribunal reviewed the case and rejected Vondrousova’s justification, ruling that her stress and mental health concerns did not constitute a compelling reason to evade testing. While Vondrousova explained that poor mental health had affected her decision-making, the agency determined that such factors were not sufficient to override the requirement to submit to testing. The ITIA noted that refusing or evading a test carries a starting point of a four-year suspension.
Vondrousova, who has not played competitively since January and has dropped to 122nd in the rankings, maintains her innocence. In a statement, she wrote that she has never doped and has always stepped onto the court with a clear conscience. She added that she cannot say what comes next and, for the first time in her life, does not have a plan. The ITIA confirmed that Vondrousova signed a refusal form shortly after the incident while outside walking her dog.
ITIA chief executive Karen Moorhouse emphasised the necessity of the agency’s stance, stating that it is essential to protect fair competition. Moorhouse argued that the anti-doping system cannot allow a player to be in a better position by refusing a test than by taking one and testing positive. Vondrousova retains the right to appeal the decision to the Court of Arbitration for Sport, though any appeal is likely to take many months, ensuring she will miss the upcoming Wimbledon tournament.
