Overview
- The governing agency says the out‑of‑competition test attempt took place on Dec. 3, 2025 when a doping control officer visited Vondrousova’s home at about 8 p.m. and she did not submit a sample.
- An independent tribunal concluded the evidence she offered provided “no compelling justification” and imposed a four‑year ban that runs until June 21, 2030.
- While suspended she is barred from playing, coaching or attending events organised or sanctioned by the ITF, WTA, ATP, the Grand Slams, or any national association.
- Vondrousova has repeatedly denied doping, cited acute stress, generalized anxiety and fear for her safety in testimony and public posts, and noted a negative test three days after the incident.
- The ITIA defended unpredictable testing as essential to stop evasion and said refusal carries the same baseline sanction as a positive test; the agency and Vondrousova may seek a Court of Arbitration for Sport appeal and the tribunal’s full written reasons are expected next.
