The Football Association is seeking clarification from Chelsea and Mykhailo Mudryk after footage showed him using a racial slur in a social media post.
Mudryk has apologised after using the term while reciting a rap song on TikTok last July.
The FA is seeking clarification and observations from Mudryk and his club over when the recording was made, when it was posted online and when it was deleted.
The governing body is able to charge players for discriminatory behaviour away from a football setting under new guidelines issued in 2020.
Acts of discrimination can be classed as aggravated breaches of FA Rule E3.1 governing misconduct, and where a charge is issued and proven for such a breach, the starting sanction is six matches.
Sky Sports News has contacted Chelsea.
Mudryk’s representative told The Sun: “Mykhailo is deeply sorry for any offence caused by the video.
“His intention was to solely recite the lyrics of a song. Mykhailo regrets his decision and wholeheartedly accepts it’s not appropriate.”
Kick It Out said in a statement: “Kick it Out condemns the use of all racial slurs, irrespective of context. The use of this term by high-profile figures in football can only serve to alienate people from the game.”
