Red Star Belgrade have been banned from selling tickets to their fans for the club's next two Champions League away games because of crowd trouble during last month's play-off tie at Salzburg.
Red Star were charged with several offences, including a pitch invasion by fans who also set off fireworks, as they came back from two goals down to draw 2-2 and reach the group stage on away goals at Salzburg's Red Bull Arena.
UEFA's disciplinary committee also fined the Serbian club €30,000 and ordered them to contact Salzburg within 30 days to pay for damages caused by their supporters.
Red Star fans will not be allowed to buy tickets for the Champions League Group C games at Paris St Germain on 3 October and Liverpool on 24 October.
Serbian champions Red Star, who won the European Cup in 1991, have got to the group stage for the first time since the Champions League was launched in 1992.
Earlier this week they pledged to protect Xherdan Shaqiri from "unwanted situations" when the Liverpool winger arrives for their Champions League group match in November.
Shaqiri courted controversy during the World Cup when he celebrated a last-minute winner against Serbia with an 'Albanian Eagle' gesture.
He and Swiss team-mates Granit Xhaka and Stephan Lichtsteiner were all fined for unsporting behaviour for making the gesture, which symbolises the Albanian flag.
"Personally, I can't imagine that an Albanian will play for Red Star," the club’s general director Zvezdan TerzicTerzic told Belgrade newspaper Kurir.
"Red Star is a Serbian club, Partizan (Belgrade) was Yugoslav.
"I think that Shaqiri will be under unbelievable psychological pressure because he will know where he is coming; he knows that the Red Star is a symbol of Serbia and playing the Marakana, I don't know whether he will play.
"Of course, as a soccer club, we treat our rivals equally, and we do not have to deal with the past and the history."
