Overview
- Former Wimbledon champion Marketa Vondrousova has formally appealed her four-year ban to the Court of Arbitration for Sport and CAS has confirmed receipt but not set a hearing date.
- The International Tennis Integrity Agency imposed the June suspension after saying an anti-doping officer was denied entry for an out-of-competition test at Vondrousova’s home on December 3, 2025.
- An independent tribunal found she offered “no compelling justification” for the refusal and noted she walked her dog about 10 minutes after the officer arrived.
- Vondrousova denies any doping, says she was frightened when the officer rang the bell and later recorded a negative test taken three days after the incident.
- The case has left the 27-year-old sidelined since January with her ranking around 153 and has prompted debate among players and officials over testing protocol, athlete safety, and consistency of sanctions.
