Zlatan Ibrahimovic will miss the Scudetto showdown with Inter after the Milan man was banned for three matches.
The Diavolo sensation was dismissed in yesterday's 1-1 draw with Bari after clashing with Marco Rossi.
The League's disciplinary panel viewed the incident today and ruled it was an act of violent conduct.
Ibra will thus miss the games against Palermo, his former club Inter in what may be a Scudetto decider, and Fiorentina.
Milan are expected to launch an appeal against today's decision.
There were three match bans too for Parma's Daniele Galloppa after his red against Napoli and Lazio's Stefan Radu for his dismissal in the derby against Roma.
Cristian Ledesma, also sent for an early bath at the Olimpico, has been punished with a two-game stop for his red and verbal abuse directed at the referee.
