mudryk is back at the center of a case that has stretched from a routine urine test to a legal fight now moving through the Court of Arbitration for Sport. For Chelsea, it means another period of waiting. For Shakhtar Donetsk, it carries a financial consequence that is already being measured in millions.
What is happening in Mudryk’s appeal?
Chelsea winger Mykhailo Mudryk has lodged an appeal with the Court of Arbitration for Sport against a four-year drugs ban imposed by the Football Association. CAS said it received the appeal on 25 February 2026 and that the two sides are exchanging written submissions, with a hearing still to be scheduled.
The case has been quiet publicly, but its timeline is now clear. Mudryk was provisionally suspended in December 2024 after an adverse finding in a routine urine test. He was later charged in June 2025 and then given the maximum four-year ban by the FA. In cases like this, bans are typically backdated to the start of the provisional suspension, which would point to a return date around December 2028.
There is, however, another possibility being discussed around the player: sources close to him are hopeful he could return as early as next season if the appeal changes the outcome. For now, that remains uncertain. Chelsea has declined to comment while the process continues, and the FA has said it cannot discuss an ongoing case.
Why does the case matter beyond one player?
The story has grown into a wider issue because of what sits behind it: a major signing, a confidential anti-doping process, and a player who has not played a competitive match since November 2024. Mudryk’s last appearance for Chelsea was away at Heidenheim in the Conference League. Since then, his football has been replaced by legal process, fitness work, and waiting.
He joined Chelsea in January 2023 for an initial 70 million euros, and later reporting put the fee at £88 million. That investment now hangs over a case that has already lasted nearly 18 months. Mudryk has maintained that he never knowingly used any banned substances or broke any rules, and he described the positive test as a complete shock.
The substance involved was meldonium, a cardiovascular medication that can increase respiratory capacity and stamina. The understands Mudryk came into contact with it while on duty with the Ukraine national team in October 2024. Mudryk believes his sample was contaminated during that period. The details have not been publicly disclosed by the FA, which has never set out the full case.
What are Chelsea, Mudryk and the specialists saying?
Mudryk is being defended by Morgan Sports Law, a firm that has worked on major sporting investigations involving Paul Pogba, Tyson Fury and Chris Froome. His legal team has also been contacted for comment. Chelsea has taken a restrained line, saying it will let the process take its full course.
Sky Sports News chief correspondent Kaveh Solhekol said the public only knows the ban has been appealed because CAS confirmed it. He said the FA, Chelsea and Mudryk’s lawyers have all stayed silent because the process is confidential. He also noted that Mudryk gave the sample while on international duty with Ukraine, not while playing for Chelsea.
On his own side, Mudryk has tried to stay ready. He is understood to want to return to football this year and has been training at non-league Uxbridge FC with a private coach, with hired goalkeepers also working with him. He has also been keeping fit away from Chelsea’s Cobham training ground.
How is Shakhtar Donetsk affected by Mudryk’s future?
The financial dimension reaches back to Ukraine. Shakhtar Donetsk director Sergei Palkin said the case could cost the club 30 million euros because of performance-related bonuses linked to the transfer. He described that amount as a big financial impact, and said the club does not know when the final decision will come.
Palkin said everybody is waiting for the court’s decision and that he believes Mudryk will return to playing. That hope is tied to a broader reality: one player’s suspension can affect not only his own career, but the budgets and expectations of the clubs connected to him.
At the heart of it all sits a stalled career and a question still unanswered. Mudryk’s appeal is now in CAS, his club is staying quiet, and Shakhtar is counting the cost. Back at Heidenheim, where he last played in November 2024, that final touch now feels less like an ending than a pause.
