CAS Clears Chelsea’s Mykhailo Mudryk to Return After Doping Ban Appeal

Chelsea winger Mykhailo Mudryk has been cleared to resume competitive football with immediate effect after the Court of Arbitration for Sport (CAS) partially upheld his appeal against a doping ban.

Mudryk had been provisionally suspended following an adverse analytical finding for the banned substance meldonium and was widely reported to have received a four-year ban. The Ukrainian international has not featured in competitive football since November 2024.

CAS ruled that the 24-year-old could return to action after he accepted responsibility for breaching anti-doping regulations and reached an agreement that limited his period of ineligibility to the time he had already served.

In a statement, the Football Association (FA) explained that updated scientific testing standards played a significant role in resolving the case.

According to the FA, changes to the reporting criteria for meldonium mean that if Mudryk's sample had been collected and analysed under today's technical standards, it would not have been reported as a positive result.

The FA said:

"Changes have been made which, while not retroactive, mean that if Mr Mudryk's sample was collected today, the concentration of meldonium in the sample would not have been reported and no anti-doping rule violations would have resulted."

The governing body added that, with the approval of the World Anti-Doping Agency (WADA), both parties agreed to resolve the appeal.

As part of the settlement, Mudryk admitted to the anti-doping rule violations and accepted a suspension equal to the period he had already spent sidelined.

"Mr Mudryk is no longer ineligible and may return to competition with immediate effect," the FA confirmed.

Chelsea welcomed the outcome, saying the revised scientific reporting standards provided important context to the case.

In a statement, the club said it was pleased that advances in testing procedures showed Mudryk's sample would not have resulted in a positive test if it had been analysed under the current standards.

The Blues added that the resolution allows everyone involved to move forward.

Chelsea signed Mudryk from Shakhtar Donetsk in January 2023 in a deal worth £88 million, and the winger is now eligible to return to first-team action immediately.
