Four Serie A teams have been punished with suspended stadium bans following crowd trouble during the weekend's fixtures.
AC Milan, Inter Milan, Torino and league leaders Roma have all been reprimanded because of discriminatory chanting, with the sentences being suspended for one year.
The incidents occurred in Friday's top-of-the-table meeting between Roma and Napoli, AC Milan's match against Udinese at the San Siro and Inter's clash with Torino.
All of the clubs have been ordered to close some sections of their grounds, while Milan, Roma and Inter have also been fined €50,000 (£42,500).
