Former Cardiff City manager Malky Mackay and the club's ex-head of recruitment Iain Moody have been accused of sending "sexist, racist and homophobic" text messages during their time at the club.
ITV News understands that the FA has been in communication with Cardiff over the claims which surfaced in the Daily Mail.
According to the newspaper, the messages came to light after a raid on Moody's home during the club's investigations into eight transfers.
Among the allegations are claims Mackay used an offensive term about new South Korean signing Kim Bo-kyung, while another message is alleged to have made reference to a sex act with a player's female agent.
The Mail claims there were also a number of homophobic remarks among other messages reported to the FA.
The pair were expected to be reunited at Crystal Palace in the near future, where Moody is now director of football and Mackay was said to be lined up as replacement for former manager Tony Pulis.
