Burnley midfielder Hannibal Mejbri complained to the referee after Preston North End forward Milutin Osmajic made an alleged racist comment during Saturday's match between the two sides.
In a statement, Preston said Osmajic attended a meeting after the game with match officials and "strongly refuted the claims of a racist comment made towards Hannibal Mejbri".
"Preston North End utterly condemn any incidents of racism or discrimination wherever and whenever they occur, however, Milutin Osmajic categorically denies the allegations made against him today.
Burnley said Mejbri made referee Andrew Kitchen aware of the comment during the second half and the referee had registered the complaint.
Preston and Osmajic issued a denial after the Championship clash on Saturday.
