The Sweden international's recovery from injury is going better than expected and he could return to the pitch at the weekend, while Inzaghi is in line to feature against Udinese
The Swedish forward picked up the knock in the build-up toward the Champions League clash against Barcelona last week and spent the past few days in his native country recovering from the injury.
Ibrahimovic returned to Milan on Monday evening and his recovery is going faster than initially expected. He will not feature in Wednesday's match against Udinese, but could make a substitute appearance versus Cesena at the weekend.
Head coach Massimiliano Allegri then hopes to be able to include Ibrahimovic in the starting XI again in the Champions League match at home against Viktoria Plzen on September 28.
Meanwhile, Filippo Inzaghi could be included in the match squad to face Udinese in midweek.
The experienced attacker has been out of action for 10 months due to a knee injury, but impressed in training on Monday and could make the bench for Wednesday's game at San Siro.
