Preston North End striker Nathan Ellington may take action against Millwall fans.
The Daily Mail says the FA have asked Nathan Ellington whether he wants to make a formal complaint after the Preston striker alleged on Twitter that he had been racially abused during Saturday's 4-0 defeat by Millwall.
The 29-year-old called Millwall fans a "disgrace to the human race".
Preston were relegated from the Championship this week.
