Vondrousova appeals against four-year ban for refusing anti-doping test

Former Wimbledon champion Marketa Vondrousova has appealed to the Court of Arbitration for Sport (CAS) against a four-year ban issued by the International Tennis Integrity Agency (ITIA). The 27-year-old Czech player was banned after refusing to allow a doping control officer entry to her home to conduct an out-of-competition test in December 2025. The ban, which was handed down in June, is set to run until June 2030.
