The organisation admits the wording of its initial release - in which it branded the Scot's controversial texts "banter" - was "inappriopriate" and "trivialised matters"
The League Managers' Association (LMA) has apologised for the wording of a previous statement which addressed Malky Mackay's involvement in a text message scandal.
The LMA released a statement on Thursday apologising for any offence caused by Mackay's alleged comments in a series of exchanges which took place at Cardiff City with former Crystal Palace sporting director Iain Moody.
The messages which have been made public contain sentiments that are racist, anti-Semitic, sexist and homophobic in nature, but the LMA's statement caused further controversy by seemingly trying to excuse Mackay's actions as "friendly text message banter".
"The LMA apologises for some of its wording, in its release yesterday, which was inappropriate and has been perceived to trivialise matters of a racist, sexist or homophobic nature," the organisation's latest statement read.
"That was certainly not our intention. It is beyond argument that any comments that are discriminatory, even used in private, are totally unacceptable.
"The LMA remains absolutely aware of our responsibility to the game and to promote and uphold the highest standards of behaviour.
"The LMA will not be commenting further on the allegations relating to Malky Mackay whilst the FA conducts its investigation, other than to repeat that both the LMA and Malky will be co-operating fully.
"We will continue to work with all of the game's stakeholders to address the important issues of respect and discriminatory behaviour in all its forms."
Mackay and Moody were both sacked by Cardiff last season and the Welsh club have since sent a dossier to the Football Association (FA) alleging misconduct that hit the headlines as Mackay appeared on the verge of taking the vacant managerial post at Crystal Palace.
