Inter Milan will face the partial closure of the Giuseppe Meazza stadium in Sunday's city derby against AC Milan.
The Nerazzurri have been punished by the Lega Serie A and will have their north section of the stadium closed for two games - against Milan and Chievo on January 13, 2014.
Inter fans were found guilty of abusive chants directed at Napoli supporters during Inter's 4-2 loss in Naples on Sunday.
A statement from the Lega Serie A read: "Inter will also have to pay a fine of 50,000 euros for the geographically discriminatory chants by their fans towards Napoli supporters."
Inter's Curva Nord was already carrying a suspended sentence for abusive chants in the Nerazzurri's game at Torino on October 20.
