The "Finalissima" match between Spain and Argentina in Doha is in doubt after the Qatar Football Association suspended soccer tournaments indefinitely following US and Israeli attacks on Iran and retaliatory missiles fired at the Arabian Peninsula.
The contest between European champions Spain and Copa America winners Argentina was scheduled for March 27 at Doha's Lusail Stadium, with potential big-name draws including Lamine Yamal and Lionel Messi.
"Qatar Football Association announces the postponement of all tournaments, competitions and matches, effective from today and until further notice," the FA said in a statement on Sunday.
"The new dates for the resumption of competitions will be announced in due course through the Association's official channels."
The final call on whether to postpone the game rests with event organizers UEFA and CONMEBOL - soccer's governing bodies for Europe and South America respectively.
The Bahrain FA postponed all its matches until further notice, while the Asian Football Confederation on Sunday announced it was delaying Champions League Elite fixtures in the region.
The Asian Champions League Two, which is at the quarter-final stage, has also been affected, along with games in the Challenge League - Asia's third-tier continental club competition.
Beyond soccer, Euroleague Basketball also announced the cancellation of the NextGen EuroLeague qualifying tournament in Abu Dhabi, citing safety and security concerns for participants.
"After careful evaluation and ongoing consultation with relevant authorities and stakeholders, it was determined that cancelling the event is the most responsible course of action at this time," Reuters quoted the league as saying in a statement on Sunday.
The world governing body for basketball (FIBA) also called off four games in the region on Monday ahead of the second window of the 2027 World Cup Asian Qualifiers in Beirut.
The postponed games include Iraq v Jordan and Syria in Group C as well as Lebanon v India and Qatar in Group D.
