Chelsea manager Enzo Maresca says he has yet to speak to Mykhailo Mudryk since the forward was charged with violating the Football Association's anti-doping rules but insists the player retains the club's support.
Ukraine international Mudryk, 24, was provisionally suspended by the FA in December after an "adverse finding in a routine urine test" and now faces a potential four-year ban.
Mudryk, who at the time of his suspension said he was in "complete shock" and had "never knowingly used any banned substances", last played for Chelsea in November but attended the Blues' Uefa Conference League final win in Poland last month in a private capacity.
