Chelsea has confirmed the Football Association has contacted forward Mykhailo Mudryk about an adverse finding from a routine anti-doping test.

The Premier League club issued a brief statement on Tuesday confirming an investigation into the Ukrainian international after the adverse result from a urine sample.

"Both the Club and Mykhailo fully support The FA's testing programme and all our players, including Mykhailo, are regularly tested," the statement said.

"Mykhailo has confirmed categorically that he has never knowingly used any banned substances. Both Mykhailo and the Club will now work with the relevant authorities to establish what has caused the adverse finding."

Mudryk, who joined Chelsea in January 2023 for an initial fee of 62 million pounds ($124 million), has struggled for first-team opportunities this season and has largely been used as a substitute in the Premier League.

The 23-year-old issued a statement on Tuesday saying he was shocked by the adverse finding.

"I can confirm that I have been notified that a sample I provided to The FA contained a banned substance," Mudryk said on his Instagram page.

"I know that I have not done anything wrong and remain hopeful that I will be back on the pitch soon. I cannot say any more now due to the confidentiality of the process, but I will as soon as I can."

The FA has been contacted for comment.
