The FA has decided not to take any action after investigations into allegations of abuse by West Ham United and Millwall fans.
Two West Ham supporters were arrested for anti-Semitic gestures in a game against Tottenham in November.
Sky Sports News filmed Millwall fans racially abusing Leeds player El-Hadji Diouf in the same month.
An FA statement said: "No charges are to be issued to either club in relation to these isolated incidents.
"The FA advises that consideration will be given to taking disciplinary action against both West Ham United and Millwall if further reports of spectator misconduct are received."
