UEFA has canceled a meeting in Berlin this weekend where member federations were to discuss ways of opposing a Sepp Blatter-led FIFA.
UEFA President Michel Platini says it is better to await developments after Blatter announced plans to resign.
Platini also noted the "unpredictable nature" of a U.S. federal investigation into corruption in world soccer.
He says "considering new information is revealed every day, I believe it is wiser to take time to assess the situation."
The 54 UEFA member federations were expected to meet on the sidelines of this weekend's Champions League final.
At least 10 UEFA members are thought to have voted for Blatter despite Platini urging the FIFA president to resign before the election last Friday.
