Former Wimbledon champion Marketa Vondrousova has been handed a four-year suspension after refusing to undergo an anti-doping test, bringing a major setback to the career of the Czech tennis star.
The anti-doping ban follows an incident in December 2025 when Vondrousova declined to provide a sample after a doping control officer arrived at her home for an out-of-competition test. The 26-year-old argued that stress, mental health challenges and concerns about her personal safety influenced her decision.
An independent tribunal reviewed the case and considered both Vondrousova’s explanation and evidence provided by the doping control officer involved in the testing attempt. However, the panel ruled that the information presented offered no valid reason to refuse the test and upheld the charge.
Commenting on the decision, International Tennis Integrity Agency chief executive Karen Moorhouse said: “We understand that the testing process is uncomfortable, and acknowledge that it is an additional burden for players whose jobs already come with a high level of pressure and scrutiny, but it is essential to protect fair competition.
“Safety and welfare of players and our testers is really important to us. Our testers are well-trained, professional, and the gender of our testing witness always matches the player.
“They carry ID at all times, and players are able to verify their identity in other ways if they are ever unsure.”
The anti-doping ban will remain in effect until 21 June 2030. During that period, Marketa Vondrousova cannot compete in, coach at, or attend events organised or sanctioned by the ITF, WTA, ATP, Grand Slam tournaments or national tennis associations.
Vondrousova enjoyed the biggest moment of her career in 2023 when she became the first unseeded player to win the Wimbledon women’s singles title, defeating Ons Jabeur in the final. She also reached the French Open final in 2019, earned a silver medal at the Tokyo Olympics in 2021 and climbed to a career-high world ranking of sixth in 2023.
The former Wimbledon champion has played only two WTA Tour matches this year, with the anti-doping ban now set to keep her away from professional tennis for the next four years.
