The Football Association has revealed that Malky Mackay and Iain Moody will face no further action over "inappropriate" text messages sent last year.
Mackay and Moody were the subject of an investigation by the governing body over alleged racist, sexist, homophobic and anti-Semitic texts during their time at Cardiff City.
The messages, which were sent between June 2011 and March 2014, first surfaced last August. However, after an in-depth enquiry, it has been decided that the matter will not be taken any further.
"Having assessed the evidence, and in light of the finding that the communications were sent with a legitimate expectation of privacy, The FA will not be taking disciplinary action against Iain Moody and Malky Mackay in connection with the content of those messages," an FA statement read.
"However, The FA has spoken to both Iain Moody and Malky Mackay about the inappropriateness of terms used in the messages. Both individuals have acknowledged that such terms are not acceptable. Mr Mackay has also voluntarily undertaken equality and diversity training.
"The FA is in the process of carrying out a complex review involving all stakeholders on how communications, and in particular those involving discriminatory language, which may be viewed as taking place in private should be treated in the future."
Mackay made a return to management last year when taking over at Wigan Athletic, but he was dismissed in April after less than five months in charge.
