UEFA has banned Red Star Belgrade fans from buying tickets for their Champions League match at Tottenham as a punishment for racism.
European football's governing body said its disciplinary panel found the charge proven against the Serbian champions in a qualifying game against HJK Helsinki in Finland in July.
Red Star will now not be able to sell tickets for the Group B game at Spurs in London on October 22, while the club was also fined 50,000 euros (£44,500).
The punishment follows similar fan incidents last season, when charges of racist behaviour, illicit chants and crowd disorder led to Red Star playing a home playoff game in an empty stadium and being barred from selling tickets to two group-stage games away from home.
Red Star were ordered to pay UEFA fines totalling 191,000 euros (£170,000) last season, and 122,000 euros (£108,000) so far this season.
Red Star lost their opening Group B fixture 3-0 at Bayern Munich, while Tottenham drew 2-2 at Olympiakos.
