As the Serie A game is on Saturday night and the Rossoneri must also prepare for the Champions League encounter with Atletico Madrid, it is likely Kaka will be rested until he has fully recovered.
Michael Essien could possibly also receive his Milan debut in midfield.
Meanwhile, Milan midfielder Bryan Cristante will be out of action for a month after fracturing his fibula.
