Balotelli handed three-match ban
Balotelli was already automatically suspended for one match after picking up his fourth booking of the season in the 2-2 draw.
However, another two matches were added to his ban on Tuesday for insulting one of the assistant referees at the end of the game.
The Italy striker has scored 10 goals in 11 games for club and country in 2013.
Milan is third, four points behind Napoli in the fight for second place and a direct Champions League berth.
Juventus has a nine-point lead.
