Marketa Vondrousova reacts to Nick Kyrgios’ doping ban as she fights her own four-year suspension

Vondrousova has repeatedly stressed that she has never doped and pointed to the result of a test conducted just three days after the incident as further evidence supporting her position.

“I have never doped, I have never had a positive test. Throughout my entire career I have undergone countless anti-doping controls and have always stepped on the court with a clear conscience. Just three days after the incident that ultimately changed my life, I was tested again. The result was negative. Just like every test before it.”

Kyrgios' case followed a fundamentally different path. The Australian tested positive for benzoylecgonine, a metabolite of cocaine, from a sample taken in Mallorca. He told investigators that the cocaine had been used socially during a night out before he was due to play, and an independent expert from a WADA-accredited laboratory found that the level detected was consistent with his explanation.

Under the applicable rules, the default suspension was three months, but it could be reduced to one month if Kyrgios entered an ITIA-approved treatment programme. He accepted the sanction and entered the programme, meaning his suspension ended on September 3, subject to completion of the treatment.

Vondrousova now faces a fight for her career

That difference is what makes the timing of Vondrousova's social media activity particularly notable. Kyrgios is now eligible to return to tennis after a case involving an actual positive test, while Vondrousova remains suspended until 2030 despite insisting that she has never used prohibited substances.

For the Czech, the CAS appeal could therefore determine whether her career can continue on the court. Vondrousova has not competed since January and has fallen to No. 153 in the WTA rankings, with the four-year suspension threatening to remove her from professional tennis during what should still be her competitive prime.

Kyrgios, meanwhile, is already free to return after serving his shortened suspension. His own Instagram statement following the positive test was unequivocal as he accepted responsibility for what he called “a huge mistake.”

“I wanted you to hear this from me first. I recently failed a drug test in Mallorca after testing positive for cocaine. I made a huge mistake and I take full responsibility for it.”

He also apologized to his fans, family, sponsors and the children who follow him, acknowledging the example his actions could set. The ITIA has now closed the disciplinary process with a one-month suspension, while Vondrousova's much longer legal battle is still only moving toward its next stage.
