Celtic will play Lazio in the Europa League in a partially closed stadium next month after the Italian club were charged with racist behaviour by UEFA.
The charge relates to Lazio's 2-1 win over French club Rennes on October 3 at Stadio Olimpico.
UEFA has also ordered the Italian club to play one additional UEFA competition match behind closed doors, with that sanction suspended for one year.
In a statement, European Football's Governing body confirmed that Lazio will also be required to display a banner containing the wording "#EqualGame" and the UEFA logo in the closed section of the stadium.
Lazio have been hit with a €20,000 fine.
However, it does mean Celtic fans will still be able to attend the game in Rome on November 7 after being handed an allocation of 9,000 tickets.
