Chelsea winger Mykhailo Mudryk has lodged an appeal with the Court of Arbitration for Sport after the Football Association handed him a four‑year ban for a positive meldonium test.

Mudryk signed for Chelsea in January 2023 for a record £88m from Shakhtar Donetsk and still has five years left on his contract. He last appeared for the club in a 2‑0 Conference League win over Heidenheim on November 28, 2024.

If the appeal fails, Mudryk faces a ban that would last until the end of 2028, effectively ending his time at Chelsea and derailing the club’s plans to rebuild around a once‑promising talent. The silence from the FA and club has left fans and analysts speculating about the integrity of the testing process and the future of the player’s career for the season.
