Markéta Vondroušová handed four-year doping ban for refusing anti-doping test
Consensus Summary
Markéta Vondroušová, the 2023 Wimbledon champion and former world No. 6, has been handed a four-year ban by the International Tennis Integrity Agency (ITIA) for refusing an out-of-competition doping test on December 3, 2025. The suspension, which expires on June 21, 2030, was upheld by an independent tribunal that found no compelling justification for her refusal. Vondroušová, now ranked 122, has not competed since January and can appeal the decision to the Court of Arbitration for Sport. Both sources agree that the ban reflects ITIA’s stance that refusing a test carries the same starting penalty as testing positive, emphasizing the severity of such violations. Vondroušová has maintained her innocence, stating she has never doped and has always passed prior tests, including a negative result just three days after the incident. While both articles highlight her mental health struggles, the Guardian provides additional context about her initial social media response and reference to Petra Kvitova’s assault, whereas ABC focuses more on her Instagram posts detailing stress and the tribunal’s procedural findings.
