The next UEFA executive committee meeting has been delayed until June 17 due to unresolved issues with proposed venues for next year's Euro 2020.
The meeting had initially been scheduled to take place on May 27.
Euro 2020 was due to get under way across 12 different locations in June but was pushed back by 12 months because of the coronavirus pandemic.
Amsterdam, Baku, Bilbao, Bucharest, Budapest, Copenhagen, Dublin, Glasgow, London, Munich, Rome and St Petersburg were scheduled to host games.
UEFA president Aleksander Ceferin told beIN SPORTS on Sunday that nine cities have affirmed their commitment to hosting matches in 2021, though there were issues with the remaining three.
"We've had conversations with nine cities and everything is set," said Ceferin.
"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."
In order to gain greater clarity on the circumstances surrounding host venues for the tournament, the executive committee will meet three weeks later than planned.
A UEFA statement released on Monday read: "UEFA today announced that the next meeting of its executive committee, originally scheduled for May 27, has been postponed to June 17, 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."
Euro 2020 was delayed to create space for the completion of domestic leagues, the majority of which have been suspended since March due to the COVID-19 crisis.
The Bundesliga returned behind closed doors last weekend, while Premier League, LaLiga and Serie A clubs have been permitted to return to group training – though some restrictions remain in place – this week.
Top flights in France, the Netherlands, Belgium and Scotland were ended prematurely.
