Italian media report on Tuesday that Ibrahimovic suffers from overloading the left knee and is expected to pause for at least ten days.
Thus, the 40-year-old Swede will safely miss the league game on Friday against CFC Genoa.
And also for the cup game next Tuesday at Inter Milan, it will probably be nothing.
Both Milan clubs meet in the semifinals, the first leg ended 0: 0.
Ibrahimovic has been plagued by injury again and again this season.
But in the league he comes to 19 games, he achieved eight goals.
