The authorities have denied Celtic ’s request for 20,000 fans against Midtjylland, with just 9,000 to be allowed in for the crucial clash.
With all of Scotland moving to Level 0 Covid restrictions on Monday, clubs can admit up to 2,000 fans without having to ask for permission.
Any number above that requires special dispensation from local authorities and in some cases Holyrood.
With their crucial Champions League play-off first leg against FC Midtjylland coming just days after the move to Level 0, Celtic asked for 20,000 fans to be allowed at Parkhead - around a third capacity.
The club were keen to have an enthusiastic backing for Ange Postecoglou ’s first competitive game, but were left sweating over a decision.

While permission was granted for up to 12,000 fans at Hampden for Euro 2020 matches, Rangers were limited to just a sixth of that for their friendly with Arsenal.
And it’s now been announced that Glasgow City Council have granted permission for 9,000 fans to be present to cheer on their side
A statement said: “Following today’s meeting with the local Safety Advisory Group, we have been informed that around 9,000 supporters will be permitted access to Tuesday night’s UEFA Champions League second qualifying round first leg match against FC Midtjylland at Celtic Park.
Clearly, we have worked tirelessly in this area, we had pushed for many more fans to be given access and of course we are disappointed that more supporters will not be able to attend.
"However, we really look forward to welcoming our fans for the match on Tuesday, as we do on Saturday when we meet Preston.
"We can assure our supporters we will be doing all we can to work closely with the relevant authorities and welcome our fans back in even greater numbers in the coming weeks. "
Celtic are in the second qualifying round of the Champions League, meaning they’ll have to negotiate three two-legged ties if they are return to the group stage for the first time since the Brendan Rodgers era.
