UEFA has postponed a potentially key meeting of its Executive Committee until June 17, European football's governing body said on Monday.
The meeting was initially due to be held on May 27 but has been put back due to concerns surrounding some of the venues for the next European Championship.
UEFA cited "some remaining open points regarding a small number of proposed venues for the rearranged UEFA Euro 2020 next year."
"So we will discuss further, and in principle, we will do it in 12 cities. But if not, we are ready to do it in 10, nine or eight."
