The play-offs to determine the final spots for the European Championship are likely to take place in October and November, according to Football Association of Ireland (FAI) CEO Gary Owens.
The coronavirus pandemic led to the postponement of Euro 2020 for 12 months, with the play-off fixtures that were scheduled for March having also been called off.
With no confirmed date for when international football will return, it remains to be seen when those matches will be held.
The Republic of Ireland are among the teams waiting for official confirmation, with Slovakia their opponents and either Bosnia-Herzegovina or neighbours Northern Ireland awaiting the victors.
UEFA held an update with its member nations via teleconference on Tuesday, with FAI chief Owens offering an update on when the play-off games will go ahead after that meeting.
Owens told FAI TV: "There has been a slight move on that [play-off dates]. Originally, we thought it may well be November but it now looks like the semi-final is the preferred option in October.
"They don't want to have the semi-final and the final of the play-offs in the one month. It looks like the Nations League matches will be in September and October, with the semi-final play-off in October and the final play-off in November."
Earlier on Tuesday, UEFA announced it is to produce new guidelines outlining qualification criteria for its competitions from domestic leagues that cannot be completed.
However, the governing body once again recommended competitions should be finished if possible.
