Red Star Belgrade have been banned from selling tickets to supporters for their Champions League Group C game at Liverpool on 24 October.
Serbia's champions came from 2-0 down to draw 2-2 at RB Salzburg on 29 August and make the group stage on away goals.
Red Star faced several Uefa charges, relating to a pitch invasion and the setting off of fireworks.
Uefa has told Red Star not to sell tickets to fans for the next two Champions League away games.
The visit to Anfield is Red Star's second away group game, coming after they visit Paris St-Germain on 3 October.
Uefa's disciplinary committee also fined Red Star £26,824 (30,000 euros) and ordered them to contact Salzburg within 30 days to pay for damages caused by supporters.
