Chelsea forward Mykhailo Mudryk has appealed his four-year doping ban to the Court of Arbitration for Sport, according to reports in British media.

The Ukrainian, 25, was charged with anti-doping rule violations in June last year after a sample taken in 2024 tested positive for meldonium, the same substance that led to Maria Sharapova’s suspension.

Mudryk has maintained the finding came as a "complete shock," saying he never knowingly used a banned substance.

The CAS confirmed it received the appeal on February 25, 2026, with written submissions currently being exchanged. A hearing date has yet to be set.

Mudryk joined Chelsea from Shakhtar Donetsk in January 2023 for an initial fee of 70 million euros and has been provisionally suspended since December 2024.
