Celtic and Rangers fans have been warned not to start booking travel for their European campaigns, as away supporters may be barred.
The draw for the Europa League group stage was made on Friday, with tough groups for both of Scotland's representatives.
There are also some plum away trips though, with Rangers drawing Sparta Prague and Celtic headed to Budapest to face Ferencvaros.
In ordinary times those would be sure to have fans flocking for cheap pints in Eastern Europe, but with coronavirus restrictions still in place across the continent that may not be allowed.
And fans of the Premiership pair have been told not to start booking flights and accommodation as they may not be allowed to attend the matches.
A statement from the governing body said: "The current rule not to allow travelling fans at UEFA club competitions matches is currently being reviewed by UEFA and a subsequent decision will be communicated in the next days.
"We advise fans to not make any travel arrangements before a decision has been communicated."
As well as their trip to Hungary, Celtic will face Bayer Leverkusen and Real Betis.
Rangers will take on Brondby and Lyon as well as going to the Czech Republic.
