Former Wimbledon champion Marketa Vondrousova has been handed a four-year ban from professional tennis after refusing an anti-doping test in December 2025. The International Tennis Integrity Agency (ITIA) confirmed the suspension for the 26-year-old Czech player, which will see her sidelined from the sport until 21st June 2030. Vondrousova, who made history in 2023 as the first unseeded player to win the Wimbledon women's singles title, was charged by the ITIA after she denied a doping control officer entry to her home to conduct the test.
Vondrousova stated in April that she feared for her safety when the officer called, claiming they failed to adhere to established protocol. She also cited the traumatic knife attack on fellow Czech player Petra Kvitova in 2016 as a reason for her apprehension. However, an independent tribunal concluded that Vondrousova provided "no compelling justification" for her refusal. During the hearing, the former world number six also cited stress and poor mental health as factors influencing her decision-making.
Karen Moorhouse, chief executive officer of the ITIA, acknowledged that the testing process can be "uncomfortable" but emphasised its critical role in "protecting fair competition." Vondrousova, who has not competed since January and has seen her ranking drop to 122nd, maintained her innocence in a statement, asserting: "I have never doped, I have never had a positive test. Throughout my entire career I have undergone countless anti-doping controls and have always stepped on to the court with a clear conscience." She added that for the first time in her life, she does not have a plan for her future.
The ITIA clarified that all doping control officers carry identification and a letter of authority, and players can request an additional unique ID code for verification. Nicole Sapstead, ITIA senior director, insisted that Vondrousova's presented evidence regarding stress and mental health issues was not deemed sufficient to justify her refusal of the test. The agency highlighted that refusing a test is considered a serious offence, carrying the same four-year ban as a positive test for a banned substance, to prevent players from gaining an advantage by evading testing.
This significant ban for a recent Grand Slam winner sends a stark message across the tennis world regarding adherence to anti-doping regulations. Vondrousova retains the right to appeal the tribunal's decision to the Court of Arbitration for Sport (CAS). The case underscores the stringent approach taken by anti-doping authorities to maintain integrity within professional sport.
