The 26-year-old Czech was sanctioned on Monday after an independent tribunal ruled she had failed to comply with an out-of-competition anti-doping test in December 2025 by not allowing an anti-doping officer to conduct the control.

Vondrousova, who won Wimbledon in 2023, rejected any suggestion of wrongdoing in an emotional statement posted on social media.

"I have never doped. I have never had a positive test," she wrote.

"Throughout my entire career, I have undergone countless anti-doping controls and have always stepped onto the court with a clear conscience."

The former world No. 6 said she had been tested again three days after the incident, with the result returning negative.

In April, Vondrousova claimed she had been frightened when an officer arrived at her home without properly identifying themselves or following the correct procedure.

However, the tribunal ruled that the evidence presented offered "no compelling justification" for refusing the test.

Her lawyer, Jan Exner, confirmed the player is considering an appeal but declined to provide further details.

'Exhausting and painful'

Vondrousova described the past several months as one of the most difficult periods of her life.

"I would not wish what I have been through on anyone," she said.

"Waking up every day with uncertainty, fear and the feeling that you are losing control over your own life is difficult to put into words."

Under the terms of the suspension, Vondrousova is barred from playing, coaching or attending events sanctioned by the ITF, WTA, ATP, Grand Slams and national tennis associations.

The ruling has also drawn criticism in the Czech Republic.

Vladislav Savrda, manager of Vondrousova's Prague club, labelled the decision "nonsensical and scandalous", arguing that the punishment was disproportionately severe compared to recent cases involving leading players.

Vondrousova enjoyed a breakthrough career highlighted by her Wimbledon triumph in 2023. She also reached the French Open final in 2019, won Olympic silver at the Tokyo Games and claimed three additional WTA singles titles.

Injuries have limited her appearances this season, with the Czech playing only two matches before withdrawing from the Adelaide International in January due to a shoulder problem.
