UEFA has charged Spartak Moscow player Leonid Mironov with racist behavior for allegedly verbally abusing a Liverpool opponent in the youth version of the Champions League.
UEFA says its disciplinary body will judge the case at a date to be confirmed.
According to UEFA regulations, Mironov faces a ban of "at least 10 matches or a specified period of time."
The Liverpool and Spartak Moscow youth teams played on Wednesday before the English club's 7-0 win in the Champions League.
Never miss a local story.
Liverpool striker Rhian Brewster was visibly angry and restrained by teammates and coaches at the final whistle of a 2-0 win.
UEFA punished Spartak by closing a section of the stadium for one youth-team game after fans racially abused Brewster's Liverpool teammate, Bobby Adekanye, in Moscow in September.
