A Government spokesman has confirmed that the Government has issued a letter of support for Ireland's bid to co-host Euro 2028.
The application is a joint bid with Scotland, Wales, England and Northern Ireland.
It is understood there was no discussion regarding the cost of jointly hosting the event at the Cabinet meeting this morning.
Tomorrow is the deadline for national football associations to confirm their interest in bidding to host the event, the world's second biggest international football tournament.
Around 150,000 football fans could travel to Ireland for the tournament.
The Government will likely provide funding for venues, transport, security and fan zones.
It looks likely that the joint Ireland and UK bid may be the sole expression of interest to host Euro 2028, as UEFA has ended the Russian bid, while Turkey ended its bid to host the tournament.
Minister of State for Sport Jack Chambers has said there would be "massive economic benefits" if Ireland's joint bid to host Euro 2028 is successful, as well as "huge regional benefits" across the island.
Speaking to RTÉ's Drivetime, Mr Chambers said analysis by Deloitte has suggested there could be €300m to €600m of direct spend, with a net value of between €180m and €290m.
He said there has been significant investment in the Aviva and Croke Park in recent years, meaning there would be "limited costs there" compared to other countries that might not be able to frontload that investment.
The predominant costs would be around security and policing, he said, adding that while there might be additional specifications to stadia and there is no tournament or staging fee.
He said initial figures suggest the security cost could be between €26m and €35m.
He also said there is a contingency around inflation in all of the figures.
Mr Chambers said the GAA has had engagement with the FAI and has had "positive early discussions".
There will be a collaborative process over the next year to work through the details, he said, adding that the GAA has held "many other major events" in Croke Park.
"It could be a case that Croke Park could have one or two matches and the Aviva could host the vast majority of them," he said.
"The FAI and the GAA will have to work through that."
Ireland manager Stephen Kenny said he believes it would be a good news story for the country should Ireland prove successful with the joint venture to co-host the tournament.

Labour TD Aodhán Ó Ríordáin said he is not convinced Ireland's joint bid for the tournament is the right way to go.
Also speaking to RTÉ's Drivetime, Mr Ó Ríordáin said football is an "incredibly important game" and does an awful lot of good, but there are major problems in Irish football.
He said it has only been five years since the women's team went on strike and three years since former FAI CEO John Delaney resigned "under a cloud of controversy".
There are "massive infrastructural issues within the game" at grassroots level, he said, adding that around 30% of League of Ireland players only have a Junior Cert result as their qualification.
Mr Ó Ríordáin said football has been "poorly administered and poorly funded" in many parts of the country and it always seems to come back to a conversation about hosting a tournament.
"We could have a proper, far-reaching discussion about the nature of the game - how powerful it is, who plays it, who supports it, who needs it," he said.
"There's immense power within this game, but what we're doing now is we're going to distract everybody with this venture for co-hosting a tournament in six years' time and all these fundamental questions about where the game should be and where we've come from are going to be left unanswered."
