Leeds United goalkeeper Kiko Casilla has been accused of racially abusing Charlton forward Jonathan Leko.
The Football Association is to launch an investigation into the alleged incident, which occurred during Saturday’s Championship clash at The Valley.
The Sun claim the matter was reported to referee John Brooks and the FA will now begin their enquiries.
Under new rules brought in ahead of this season, any player found guilty of racial abuse will face a minimum ban of six matches.
Casilla, who has been capped once by Spain, joined Leeds from Real Madrid in January.
He has become a key part of Marcelo Bielsa’s side, making 29 appearances in total, and has been an ever-present this term.
Saturday’s game at The Valley ended in a 1-0 win for Charlton, moving them up to sixth in the Championship table, level on points with fourth-placed Leeds. Both Casilla and Leko started the match.
