The FAI have appointed Gary Owens as interim chief executive of the association and vowed to fill the position permanently in the coming weeks.
John Foley - a former Chief Executive of Athletics Ireland - was due to take the interim position three weeks before Christmas but chose not to take up his appointment.
He had agreed to take over from Noel Mooney, whose period at the helm of the FAI ended at the start of December.
The FAI subsequently appointed Paul Cooke as the executive lead of the association. Cooke had been elected vice president of the FAI at the AGM last July.
He will now step away from his role as Executive Lead and hand the reins to Owens, who has previously undertaken interim CEO roles with Down Syndrome Ireland and Athletics Ireland.
"The FAI can confirm that it intends to commence a recruitment and selection process to appoint a CEO in the coming weeks," a statement from the association read.
"In the meantime, the FAI board tonight approved the appointment of Gary Owens as Interim Chief Executive with immediate effect.
"Gary Owens is a highly experienced leader and non-executive director with specialist expertise in business re-structuring, turnaround strategies and governance structures.
"Gary has a distinguished career in senior management roles in the financial services and technology sectors, including IFG Group, Rainmaker Technologies and Hibernian Group. He has previously undertaken interim CEO roles with Down Syndrome Ireland and Athletics Ireland."
Roy Barrett was named Independent Chairperson of the association two weeks ago. Catherine Guy and Liz Joyce also joined the FAI board as independent directors. A fourth independent director is due to be appointed soon, with the new board tasked with finding a permanent CEO.
"Gary brings a wealth of experience to this interim role and the Board and I look forward to working with him," Barrett said of Owens' appointment.
"The Board would like to take this opportunity to sincerely thank Mr. Paul Cooke, FAI Board Member, who at very short notice held the position of Executive Lead on a pro bono basis for the past few weeks, whilst a process to identify and select an interim CEO was underway."
Earlier on Monday news broke that John Delaney has resigned from his position on the UEFA Executive Committee with immediate effect.
Delaney's time on the committee was due to end at the end of 2021.
The former FAI CEO had retained his €160,000 position with the European governing body, despite ending his association with the FAI last year.
