Lazio have been found guilty of racist chanting after their fans abused Tottenham players during a Europa League match in November, but they will only be given a suspended punishment of playing a game behind closed doors.
Disciplinary proceedings were opened earlier this month against both clubs as UEFA looked to examine the events during and surrounding the Europa League group stage fixture at the Stadio Olimpico.
A highly-visible banner held by Lazio fans proclaimed 'free Palestine', while there was also an attack on Spurs supporters the night before the match, although it was later proven to have been carried out by Roma fans.
The UEFA Disciplinary Committee met on Thursday and revealed they had told the Rome-based club that if racist chanting or banners from their supporters are seen again, then their next home game will take place in front of an empty stadium.
Their next Europa League game at home - on February 21 against Borussia Monchengladbach - will be open to fans, but will be closely monitored by the committee.
Lazio have made huge strides in recent years to distance themselves from their previous reputation of condoning right-wing messages and this latest news will be a huge blow to those efforts.
