Uefa has opened a disciplinary case against Celtic after apparent crowd disorder at their Europa League match in Croatia on Thursday.
The club's fans set off fireworks during a 4-3 loss at Dinamo Zagreb.
Uefa says its disciplinary panel will judge the case on 19 February, the same day in their Europa League last-32 first-leg tie.
This is the fifth time in three years Celtic have been charged by Uefa over supporter behaviour.
The Scottish champions were fined £12,600 in 2011 after supporters made pro-IRA chants during a Europa League home match against Rennes.
They were then handed a further £21,000 punishment after their followers unfurled a banner criticising Uefa and set off flares during a later match in the same competition away to Italian side Udinese.
The club incurred a £4,200 penalty when a firework was let off during the Champions League qualifier against Cliftonville at Celtic Park in July 2013.
And a year ago they were fined £42,000 by Uefa for "illicit" banners at the home defeat by AC Milan.
