Sandro Tonali, Roger Ibanez and Manuel Lazzari are among the players suspended for Serie A Week 18, while Sampdoria and Lazio are fined for offensive chants.
The disciplinary commission gave its verdicts after the completion of the Serie A Week 17 fixtures.
Milan will have to do without Tonali for the game against Lecce, while Roma defender Ibanez is out of the Fiorentina meeting.
Also given a one-match ban are Lazio full-back Lazzari, Salernitana defender Flavius Daniliuc, Sampdoria midfielder Tomas Rincon, Cremonese’s Leandro Sernicola and Bologna pair Gary Medel and Nicolas Dominguez.
Sampdoria have been fined €10,000 for chants of ‘territorial discrimination’ against Naples, while Lazio were fined €8,000 and Bologna €5,000 for offensive chants.
Lazio already had the Curva Nord shut during the 2-2 draw with Empoli for their racist abuse of Lecce players Samuel Umtiti and Lameck Banda.
Ban fans who chant. What do the team have to do with the idiots who chant?
