Former Wimbledon champion Marketa Vondrousova is banned for four years for refusing an anti-doping test in December 2025.

Marketa Vondrousova beat Ons Jabeur in the Wimbledon women's singles final three years ago Former Wimbledon champion Marketa Vondrousova has been banned for four years for refusing an anti-doping test last year. Vondrousova, 26, was charged by the International Tennis Integrity Agency (ITIA) after denying a doping control officer entry to her home to conduct the test in December 2025. The Czech player said in April she feared for her safety when the officer called and said they failed to follow "protocol". But a tribunal determined Vondrousova, who became the first unseeded player to win the Wimbledon women's singles title in 2023, provided "no compelling justification" for refusing a test. Vondrousova's suspension will end on 21 June 2030, but she has a right to appeal against the decision to the Court of Arbitration for Sport (Cas). Under anti-doping rules, the starting point for a sanction when a player refuses a test is the same as if they had tested positive. During the hearing, Vondrousova explained stress and poor mental health had affected her decision-making, in addition to her safety concerns.
