The Football Association has announced its investigation into Malky Mackay and Iain Moody's exchange of racist, sexist, homophobic and anti-Semitic messages has been extended after new information was passed to the governing body.
The FA investigation into the messages, sent when Wigan manager Mackay and Moody were together at Cardiff, dates back to August and officials had been hoping to bring the case to a resolution in the next few weeks.
But the FA, in a statement released to Press Association Sport, said: "Due to the emergence of significant new information The FA is currently not in a position to conclude its ongoing enquiries into the allegations relating to Malky Mackay and Iain Moody."
Mackay was sacked by Cardiff in December 2013 after falling out with owner Vincent Tan and seemed set to fill the Crystal Palace vacancy before the text messages were disclosed in August.
The 43-year-old Scot became manager of Cardiff's Championship rivals Wigan in November but has been unable to steer them away from relegation trouble.
Cardiff's board members did not sit in the directors' box during their 1-0 win at Wigan last week in a show of sympathy to Tan over the alleged racist comments made by Mackay and Wigan owner Dave Whelan.
Instead, club chief executive Ken Choo and director Steve Borley watched the game behind the goal with the Cardiff fans at the DW Stadium.
