Russia could be stripped of the Champions League final as early as Friday after UEFA convened an emergency meeting.
The showpiece event of European club football is scheduled to be held at the Krestovsky Stadium in Saint Petersburg on May 28.
But Russia's invasion of Ukraine, which started on Thursday morning, means it is highly likely the final is moved, with three London venues - Wembley Stadium, the Tottenham Hotspur Stadium and West Ham's London Stadium - potential options.
A UEFA statement said: 'Following the evolution of the situation between Russia and Ukraine in the last 24 hours, the UEFA President has decided to call an extraordinary meeting of the Executive Committee for Friday 25 February at 10:00 CET, in order to evaluate the situation and take all necessary decisions.
