Mykhailo Mudryk has tested positive for a banned substance.
Chelsea confirmed the “adverse finding in a routine urine test” on Tuesday morning and said Mudryk “has confirmed categorically that he has never knowingly used any banned substances”.
Mudryk allegedly tested positive for meldonium following international duty with Ukraine in November. Meldonium is an anti-ischemia medication, which, according to USADA (the United States Anti-Doping Agency), is typically used clinically to treat “those suffering from heart conditions, such as low blood flow to the heart and angina”. For athletes, it can assist with endurance and the capacity to recover from exercise.
