UEFA charged Barcelona midfielder Sergio Busquets yesterday with racially insulting Real Madrid defender Marcelo during the Champions League semi-finals.
Busquets faces being banned for the 28 May final against Manchester United if the charge is proven.
UEFA said its disciplinary panel will hear the case on Sunday, and Barcelona will be told the verdict the next day.
Busquets is alleged to have violated UEFA's discrimination rules "by directing racist abuse toward" Marcelo, who is black.
UEFA said it took statements from Marcelo and Madrid and used video evidence of an incident when the two players clashed.
