Former Wimbledon champion’s suspension comes as Mykhailo Mudryk returns for Chelsea, exposing stark contrast in processes

In the months between the first announcement of Marketa Vondrousova’s doping test refusal and the release of the full reasoned decision after her four‑year ban, the 2023 Wimbledon champion did her best to grab hold of the narrative. Between her social media posts and later interviews, Vondrousova explained that she had serious concerns about her safety during the encounter, that the doping control officer at her door had acted improperly, and that her mental health problems had affected her judgment.

Then came the 58-page document, a summary of the court tribunal process, which was finally released a little over a week ago. Among the ample questionable decisions it showed Vondrousova to have made that evening, the text to her boyfriend shortly after the doping control officer arrived was particularly revealing, an indication that she felt disdain towards the tester rather than fear: “So like here is ringing some cunt from the doping,” she wrote.

• Bild claims acid injections used to alter jumpers’ suits

• ‘If anything was to come to the surface we’d look at it’

During its 26-year history, the World Anti-Doping Agency has faced thousands of questions about athletes using illicit substances. Thursday, however, surely marked the first time it was asked whether ski jumpers were injecting their penises with hyaluronic acid in order to fly further.

The Wada president Witold Banka’s reaction? “Ski jumping is very popular in Poland [Banka’s home country] so I promise you I’m going to look at it,” he said, with a wry smile.

• Howman: ‘We are not effective enough at catching cheats’

• Former Wada director general urges more ambition

One of the most senior figures in global anti-doping has warned that too many drug cheats in sport are evading detection – and criticised the current system as “ineffective”.

David Howman, the former director general of the World Anti-Doping Agency (Wada) and the chair of the Athletics Integrity Unit, urged anti-doping bodies to be more ambitious in catching elite athletes again rather than focusing on compliance issues.
