Doping: Marketa Vondrousova Receives Four-Year Tennis Ban

Former Wimbledon champion Marketa Vondrousova has been suspended for four years after refusing to provide a sample during an anti-doping test.

The International Tennis Integrity Agency (ITIA) confirmed on Monday that Marketa Vondrousova received a four-year ban following her refusal to submit a sample during an out-of-competition doping test at her home in December 2025. The ruling means the Czech player will remain out of the sport until 21 June 2030.

The 26-year-old explained that stress, poor mental health and concerns about her safety influenced her decision not to comply with the testing request. However, an independent tribunal reviewed her claims alongside evidence provided by the Doping Control Officer involved in the visit.

After examining the case, the tribunal determined that the evidence offered “no compelling justification” for refusing the test. As a result, the Marketa Vondrousova ban was upheld, leading to one of the most significant disciplinary actions in recent women’s tennis.

Commenting on the decision, Karen Moorhouse, Chief Executive of the ITIA, highlighted the importance of maintaining the integrity of the anti-doping system. She 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.”

She also stressed that player welfare remains a priority and noted that testing personnel are trained professionals whose identities can be verified if concerns arise.

During the Marketa Vondrousova ban, she 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 several notable achievements during her career. She became the first unseeded woman to win the Wimbledon singles title when she defeated Ons Jabeur in the 2023 final. She also reached the French Open final in 2019, won a silver medal at the Tokyo Olympics in 2021 and climbed to a career-high world ranking of sixth in 2023.
