Lecce Coach Gigi De Canio and Lazio boss Edy Reja receive touchline bans for dissent, while Zlatan Ibrahimovic is suspended for Milan.
Serie A is on its winter break, but will return on January 6 with Week 18.
Touchline bans mean both Lazio's Reja and Lecce's De Canio will be in the stands for their games after protesting against the referees.
Milan face Cagliari without star striker Ibrahimovic, who was booked in the 1-0 home defeat to Roma.
Juventus have two players suspended, Leonardo Bonucci and Manuel Giandonato.
The others on a ban for Serie A Week 18 are Marco Rossi (Genoa), Mehdi Benatia (Udinese), Alessandro Lucarelli (Parma) and Andrea Mantovani (Chievo)
