Marketa Vondrousova, the 2023 Wimbledon champion, has been handed a four-year suspension after failing to provide a sample during a doping control attempt in December.
Former Wimbledon singles winner Marketa Vondrousova was issued a four-year ban on Monday after refusing to comply with an anti-doping test.
The incident occurred in December 2025, when the player declined to submit a sample during an out-of-competition test conducted at her residence by a doping control officer.
The 26-year-old Czech star, who made history by winning Wimbledon in 2023, argued that her decision was driven by concerns regarding her personal safety and the impact of “months of physical and mental stress.”
In an Instagram post from April, Vondrousova expressed fear regarding the late-evening arrival of the doping officer, claiming they failed to properly identify themselves or adhere to standard protocols.
“In that moment, my priority was feeling safe, rather than avoiding any testing,” she stated.
Under professional regulations, players must maintain a daily “whereabouts” log to facilitate unannounced anti-doping tests outside of tournament play.
An independent tribunal reviewed Vondrousova’s defense alongside testimony provided by the doping control officer involved in the attempt.
The tribunal ultimately ruled that the evidence provided by the world number 122 did not offer a “compelling justification” for the refusal.
Karen Moorhouse, CEO of the International Tennis Integrity Agency, commented: “While we recognize that the testing process can be uncomfortable and places an additional burden on players facing high levels of pressure, it remains essential for ensuring fair competition.”
“The safety and welfare of both our players and testers are paramount. Our testers are highly trained professionals, and we ensure the gender of the testing witness always matches the player. They carry identification at all times, and players have multiple ways to verify their identity if they have any doubts.”
Vondrousova’s suspension is set to remain in effect until June 21, 2030.
Potential for Appeal
Throughout the duration of the ban, the Czech player is prohibited from competing in, coaching at, or attending any events sanctioned by the ITF, WTA, ATP, Grand Slam tournaments, or any national tennis associations.
Vondrousova is currently evaluating the verdict to determine if she will lodge an appeal with the Court of Arbitration for Sport (CAS).
“Marketa has asked me—and I wish to respect her wishes—to refrain from making any comments at this stage,” Vondrousova’s legal counsel, Jan Exner, told AFP.
“Once we have reviewed the full explanation of the verdict, we will decide on our next steps, including whether to appeal. My priority is to consult with Marketa before speculating on any further legal actions.”
A three-time WTA Tour singles champion, Vondrousova rose to prominence as the first unseeded player to win the Wimbledon women’s singles title, defeating Ons Jabeur in the final three years ago.
Her notable career achievements also include reaching the 2019 French Open final and winning a silver medal at the 2021 Tokyo Olympics.
Vondrousova reached a career-high ranking of world number six in 2023. Her recent season has been limited, having played only two WTA Tour matches after withdrawing from the Adelaide International in January due to a shoulder injury.
