Wales' crucial World Cup play-off this month has been thrown into doubt amid Russia's invasion of Ukraine.
FIFA has confirmed that Ukraine has requested to postpone its World Cup play-off with Scotland on March 24.
The nations were due to meet at Hampden later this month, but football in Ukraine has been suspended following Russia's invasion of the country.
The winners of the match had been set to play either Wales or Austria - who play each other on the same day - for a place at Qatar 2022, but the play-off path now looks uncertain.
"FIFA can confirm it has received a request from the Ukrainian Association of Football to postpone their matches scheduled for March," a statement said on Thursday.
"FIFA remains in regular contact with UEFA and the Scottish Football Association to find an appropriate solution.
"FIFA expresses its deepest solidarity to everybody affected by what is happening in Ukraine. A further update will be provided in due course."
Earlier this week, Scottish FA president Rod Petrie wrote "football is inconsequential amid conflict" in a message to his Ukrainian counterpart.
