Overview
- The International Tennis Integrity Agency announced on Monday that a tribunal suspended Marketa Vondrousova for four years after she refused an out-of-competition test at her home on December 3, 2025.
- Under the anti-doping rules cited by the ITIA, a refusal to provide a sample is equated with a positive test and carries the same maximum four-year sanction.
- The ban runs through June 21, 2030, and the player, the ITIA or the Czech national anti-doping organisation may appeal the decision to the Court of Arbitration for Sport.
- Vondrousova has said on Instagram that months of physical and mental stress, online threats and a late-night visit left her afraid and led her to refuse the test, but the ITIA tribunal found those explanations insufficient.
- The suspension removes a recent Grand Slam champion from competition, freezes her ranking slide she has faced since January, and risks long-term damage to her career unless an appeal overturns the ruling.
