Inside Mudryk doping case: lawyers, meldonium and an uncertain timeline

Mykhailo Mudryk, the 24-year-old Chelsea winger, remains provisionally suspended and is unable to play for club or country after being charged by the Football Association over a doping offence, the FA confirmed. A urine sample taken in December 2024 returned a positive result for a banned substance, and Mudryk was formally charged in June as the investigation continues with no defined timetable for a conclusion.

BBC Sport has reported that the substance involved is meldonium, a cardiovascular medication banned by the World Anti-Doping Agency (WADA) since 2016. Mudryk and his legal team deny he knowingly ingested any banned substance. In an Instagram post after the positive test became public, Mudryk said: "This has come as a complete shock as I have never knowingly used any banned substances or broken any rules, and am working closely with my team to investigate how this could have happened." His defence is being managed by Morgan Sports Law, a firm that has represented high-profile athletes in previous anti-doping cases.

People close to Mudryk say he has passed an unverified lie detector test asserting he did not knowingly take a banned substance. BBC Sport has been told Mudryk came into contact with meldonium while with the Ukraine national team, though the Ukrainian Association of Football (UAF) said it could not comment because it is not a party to the case and that WADA or the FA had not made a formal request to the UAF. The UAF added it was providing Mudryk’s lawyers with information and that no UAF official, doctor or coach was involved.

Mudryk has not played since Nov. 28, 2024. He was an unused substitute three days later. He remains in London and has restricted access to Chelsea facilities while provisionally suspended, training privately with a personal coach to maintain fitness. Those close to him describe his physical and mental health as stable and note he frequently attends church.

The potential consequences are severe: an athlete found to have committed an anti-doping rule violation can face a ban of up to four years. The FA handles doping matters confidentially, which limits public detail on the stage of the inquiry or the evidence under review. If found guilty, Mudryk could appeal to the FA's anti-doping tribunal and, after that, seek a further appeal to the Court of Arbitration for Sport in Switzerland. The case of Paul Pogba, whose legal team also used Morgan Sports Law, illustrates the possible length of the process; Pogba’s situation took about 18 months from an initial positive test to a return to playing after an appeal reduced his sanction.

The case carries broader consequences for Ukraine and for clubs involved in Mudryk’s career. His absence has fuelled frustration in Ukraine as the national team, without him, drew with Azerbaijan and lost at home to France during recent qualifiers, leaving their 2026 World Cup prospects in jeopardy. Shakhtar Donetsk, Mudryk’s former club, stands to forfeit potential transfer add-ons estimated at up to €30 million tied to performance conditions that are unlikely to be met while he is sidelined. Shakhtar executives, including sporting director Dario Srna and CEO Sergei Palkin, have publicly expressed moral support for Mudryk and rejected reports that the club intends to sue the UAF over lost earnings.

Chelsea have limited their public comment while the FA process unfolds. The club is monitoring Mudryk’s fitness but is constrained by the terms of his provisional suspension on how it can assist. Legal teams for Mudryk have been engaged in building a defence, and the player’s camp says it is cooperating with investigations.

There is no set timetable for resolution. Doping investigations proceed until governing bodies have reviewed and adjudicated the available evidence, and the FA’s confidentiality means that supporters and observers may have to wait weeks or months before learning whether Mudryk will return to the pitch or face a lengthy ban. The outcome will determine not only Mudryk’s immediate playing future but also potential financial implications for his former club and the composition of the Ukraine national team as they pursue World Cup qualification.
