Sunderland and manager David Moyes have been granted more time by the FA to explain his 'slap' comment to a female reporter.
The 53-year-old Scot issued a public apology to BBC Newcastle and Radio Five Live reporter Vicki Sparks after video footage emerged of a controversial exchange between the pair following a post-match interview where he said she "might get a slap".
Sunderland described his comments after the draw with Burnley as "wholly unacceptable" adding apologetic Moyes continued to have their full support in his role as manager.
The incident sparked widespread condemnation, with officials at the Football Association asking for the observations of Moyes and the club regarding the incident.
The FA asked to be updated by the close of play on Thursday but that deadline has now been extended until Monday afternoon.
Moyes is yet to be charged with anything, with the FA asking for observations at this stage before deciding on their next course of action.
Following the goalless draw with Burnley, Moyes was asked by Sparks if owner Ellis Short's presence at the game had meant he was under more pressure with the club once again fighting a battle against relegation.
He answered: "No, none at all" before the interview drew to a close.
However, thinking he was off camera, he then added: "You were just getting a wee bit naughty at the end there, so just watch yourself. You still might get a slap even though you're a woman.
"Careful the next time you come in."
Moyes had already apologised to Sparks before the footage of the incident entered the public domain, with the Sunderland boss again apologising at a press conference before the Leicester City defeat.
The club also issued a statement confirming their position on the matter and offering their continued backing to Moyes.
It read: "Sunderland AFC would like to reiterate the actions taken following the Burnley game on March 18.
"The exchange between the manager and a BBC reporter was wholly unacceptable and such actions are not condoned or excused in any way.
"David recognised this immediately, proactively bringing the matter to the attention of the CEO (Martin Bain) and apologising to the reporter.
"The club also spoke with both a senior figure at the BBC and the reporter personally, expressing its profound regret over what had occurred.
"The matter was treated with the utmost seriousness from the outset and the swift and decisive action taken by the club and the manager at the time ensured that it was resolved to the satisfaction of the reporter and the BBC, which was the priority.
"With both the BBC and the reporter agreeing that appropriate action had been taken at the time, the club continues to fully support David in his role as manager of Sunderland AFC."
