Vondroušová Receives Four-Year Ban for Refusing Anti-Doping Test, Eligible to Appeal

Markéta Vondroušová received a four-year suspension for refusing an out-of-competition anti-doping test at her home on December 3, 2025. Abc reported that she signed a refusal form instead of providing a sample. The ban, handed down by an independent tribunal after a June 2026 hearing, expires on June 21, 2030.

The International Tennis Integrity Agency confirmed the details of the refusal. Vondroušová has not competed in any tournament since January 2026 and currently holds a WTA ranking of 122. She remains eligible to appeal the decision to the Court of Arbitration for Sport in Switzerland.

Karen Moorhouse, ITIA chief executive, stated that the sanction aligns with rules designed to prevent players from gaining an advantage by refusing tests. "We recognise this is a significant ban," she said. " Vondroušová, 26, won the Wimbledon women's singles title in 2023 as an unseeded player after defeating Ons Jabeur in the final.

She reached a career-high WTA ranking of No. 6 that year and finished as runner-up to Ash Barty at the 2019 French Open. In an April 2026 Instagram post, she attributed the missed test to months of physical and mental stress after a testing agent arrived at her door late at night.

Abc reported that Vondroušová wrote she had never doped and had tested negative in a subsequent control three days after the incident.
