A forensic audit into finances at the FAI is being delayed.
A draft report was due to be submitted next week, but the company carrying out the audit has asked for more time.
Sport Ireland has granted the extension and has written to the Oireachtas Sports Committee warning it may take some time.
The report is examining the spending of grant money given to the FAI and wider financial administration at Irish football's governing body.
Fergus O'Dowd, chairman of the Oireachtas Committee on Sport, said he welcomed the request for further time in light of recent developments at the organisation.
Deputy O'Dowd said there's no reference in Sport Ireland's letter to departing executive John Delaney's settlement with the FAI, but he 'presumes' that will now be looked at by the auditors.
He said: "It is vital new information, and it needs to be forensically gone into.
"I'm presuming that the significant recent developments are in relation to the controversy over [John] Delaney's settlement figure.
"The auditor hasn't finished the [report]... and I think it was right and proper and appropriate that anything that happens until that is presented should go through the auditor."
Mr Delaney resigned late on Saturday night after 15 years at the the organisation.
He served as CEO from 2005 to March 2019, and as executive vice-president in recent months.
Sinn Féin's Jonathan O'Brien yesterday called for the FAI to be brought before the Oireachtas Sports Committee urgently "to explain and to answer questions" about Mr Delaney's exit package.
