FAI chief John Delaney has yet to address the fact that he has been named in court documents requesting his passport by Brazilian authorities investigating ticket touting.
The CEO of the FAI has not been contactable since Sunday when it emerged that he was one of several Olympic Council of Ireland (OCI) officials who were included in court orders signed by a judge in Rio.
Mr Delaney is the second vice-president of the OCI and has been previously tipped to eventually take over the role of president.
He spoke on radio station WLR FM yesterday to discuss the death of former FAI president Milo Corcoran, but he was not asked about developments in Rio and did not address them.
Mr Delaney was named with William O'Brien, the acting president of the OCI, and Linda O'Reilly, who works as a PA in the OCI, in documents requesting they surrender their passports.
Meanwhile, a director of the sports management agency PRO10 last night refused to answer questions on how they became the authorised seller for the OCI ahead of the Games.
Michael Glynn, a director at the sports management agency, would not discuss the issue when approached by the Herald at PRO10's offices in Lucan last night.
