UEFA have postponed a meeting of its Executive Committee amid speculation that Dublin and other host cities will be asked to stage extra games for next year's rearranged Euro 2020 tournament.
The European Football Championship, which was due to be hosted in 12 cities across Europe next month, has been deferred until summer 2021 due to the coronavirus pandemic.
UEFA said it was deferring their meeting from 27 May until 17 June due to some "open points regarding a small number of proposed venues".
Dublin remains one of the host cities after the Government reaffirmed their commitment last month, but three - reportedly Rome, Bilbao and Amsterdam - have warned they may not be able to honour their previous commitments, due to the outbreak.
Italy and Spain have been among the countries hardest hit by the virus while the Dutch government said this week that it would not allow fans to attend sporting events until a vaccine had been rolled out.
The Aviva Stadium is slated to host three Group E games, featuring Poland, Sweden and a postponed play-off winner (Republic of Ireland, Northern Ireland, Bosnia or Slovakia), followed by a last-16 tie.
The other team in group E, Spain, are due to play all three of their games at the San Mames stadium in Bilbao.
"We've had conversations with nine cities and everything is set," UEFA president Aleksander Ceferin said yesterday.
"With three cities, we have some issues. So we will discuss further. In principle, we will do it in 12 cities but if not, we are ready to do it in 10, nine or eight."
Today's statement said: "UEFA today announced that the next meeting of its Executive Committee, originally scheduled for 27 May, has been postponed to 17 June 2020, due to the existence of some remaining open points regarding a small number of proposed venues for the rearranged UEFA EURO 2020 next year."
The deferment of the meeting also means League of Ireland clubs will have to wait three weeks longer than expected to find out if and when their 2020/21 Champions League and Europa League qualifiers will take place.
Ceferin has insisted that this season's European competitions will be finished, after they were suspended halfway through the the last-16 stages.
"We have an idea but we have to wait for the executive committee of UEFA to confirm the dates," he said.
"I can say that the European season will be finished, if everything is as it is now, in August.
