Marketa Vondrousova has been suspended from professional tennis for four years following her refusal to submit to an anti-doping test, the International Tennis Integrity Agency announced. The former Wimbledon champion was charged after denying a doping control officer entry to her home in December 2025.
Vondrousova, 26, faces an extended absence from competition as a result of the violation. The Czech Republic tennis star’s refusal to cooperate with the testing procedure triggered the formal investigation by the ITIA, which oversees doping compliance across professional tennis.
Suspension Details
The four-year ban represents a significant punishment under tennis anti-doping regulations. Refusing to submit to a doping test is treated as a serious violation of the sport’s anti-doping code, with severe consequences for athletes found in breach.
Vondrousova’s suspension comes as a major blow to the player who previously reached the sport’s highest levels. Her Wimbledon championship victory represents the pinnacle of her career achievements to date.
ITIA Action
The International Tennis Integrity Agency made the determination following the incident at Vondrousova’s residence. The agency is responsible for investigating potential violations of tennis anti-doping rules and enforcing disciplinary measures against players who breach these standards.
The suspension effectively ends Vondrousova’s ability to compete in sanctioned tennis events for the duration of the ban, preventing her from participating in major tournaments and professional matches during this period.
