Stefano Pioli's Milan were due to open this weekend's round of matches in Italy's top flight at 13:00 GMT but kick-off was pushed back until 13:25 GMT.
Fourth in Serie A, Milan are three points behind league leaders Inter Milan after being thumped 5-1 by their local rivals last weekend.
The weekend's matches will be proceeded by a minute's silence in honour of former Italian president Giorgio Napolitano, who died aged 98 on Friday.
Later on Saturday Juventus take on Sassuolo before Lazio host Monza in the day's late match.
