News broke Tuesday that Chelsea and Ukraine winger, Mykhailo Mudryk tested positive for a banned substance and could be in line for a suspension.

The Chelsea forward, who cost $108 million when signed from Shakhtar Donetsk in 2023, said he had never knowingly broken any rules.

Former Russian tennis player Maria Sharapova had been the most high-profile case of an athlete being banned for using meldonium. A failed drugs test at the 2016 Australian Open led to a two-year ban issued by the International Tennis Federation, with Sharapova accepting she had made “a huge mistake” in taking the substance.
