Lazio could be forced to play a Europa League game behind closed doors following yet another charge by UEFA.
Europe's football governing body has accused Lazio fans of "racist behaviour" and "throwing missiles and/or fireworks" during the club's 2-0 victory over Borussia Monchengladbach at the Stadio Olimpico last Thursday.
The Aquile supporters were guilty of similar offences during Europa League ties against Tottenham Hotspur and Maribor earlier this season.
If UEFA does impose its punishment following a meeting on Wednesday, then Lazio would be forced to play their last 16 second-leg clash against Stuttgart on March 14 behind closed doors.
Monchengladbach fans have also been charged by UEFA for lighting fireworks inside the stadium.
