Mudryk is available again, after the Court of Arbitration for Sport, CAS, partially upheld his appeal against a four-year ban for doping.
The 25-year-old has not played a competitive match since November 2024, having been provisionally suspended by the Football Association the following month after returning an “adverse finding” for banned substance meldonium.
He was subsequently given the maximum four-year ban by the FA but appealed against the decision to CAS.
CAS has now ruled Mudryk can return to competition “with immediate effect” after he accepted breaking anti-doping rules and agreed to a suspension equal to the time already served.
Chelsea said they are looking forward to getting Mudryk back to “full fitness, back into the squad and back on to the pitch” and he will join their pre-season tour.
