Derry GAA manager Rory Gallagher has announced he is to step back from his role "with immediate effect".
Earlier, the SDLP had called for Mr Gallagher to step aside following serious allegations by his former wife.
A statement issued on behalf of Mr Gallagher this evening said: "I have advised Derry GAA that I am stepping back as Derry Senior football Manager with immediate effect.
"This decision is borne out of a desire to protect my children from the ongoing turmoil. They will always be my priority."
Cara Hunter, an SDLP Stormont Assembly member for East Derry, had said the severe allegations against him needed to be addressed.
"I think it's really important that he steps aside," she told RTÉ News.
Mr Gallagher had earlier issued a statement through his solicitor saying he had been "made aware of a social media post by my estranged wife in which she has made a number of very serious allegations against me".
He added: "Allegations against me have been investigated and dealt with by the relevant authorities."
Nicola Gallagher claimed she had been the victim of domestic violence over a period of years during their marriage, in a social media posting earlier this week.
In a statement issued this afternoon, the SDLP's Cara Hunter said she did not believe it was appropriate for Mr Gallagher to lead the Derry team ahead of the Ulster Final.
"He should do the right thing and stand aside," the statement said.
It added: "This is a test for the county board and for those in positions of leadership. There is only one acceptable outcome."
The PSNI confirmed that it investigated a number of reported incidents and files were submitted to Northern Ireland's Public Prosecution Service (PPS).
In a statement yesterday, the PPS said it had received two investigation files from the PSNI in January and June 2022 and a decision was made not to prosecute.
It said prosecutors decided there was "insufficient evidence to provide a reasonable prospect of conviction".
Derry GAA said that Ciaran Meenagh will assume the role of Derry senior football manager.
In a statement this afternoon, the Derry GAA County Board said: "Derry GAA condemns all forms of domestic violence.
"We encourage anyone who had experienced domestic violence to report it to the relevant authorities immediately."
In a statement yesterday, the GAA Ulster Council's provincial secretary and chief executive Brian McEvoy said: "While we cannot comment or make judgement on any specific allegation or allegations, Ulster GAA does not condone any form of domestic violence.
"We are proud to have joined with White Ribbon NI in pledging to never commit, condone or remain silent about violence against women. We encourage and support anyone who has been a victim of such abuse not to suffer in silence but to avail of the statutory and voluntary support services that are available in the community."
