The 32-year-old centre-half suffered a fractured kneecap during the Rossoneri's 2-1 friendly win over Valencia on Saturday night, meaning he will miss a significant chunk of the start of the new season.
"[On Sunday], following extensive investigation and after having consulted with Professor Herbert Schonhuber, the player opted for conservative treatment, with a prognosis of 70-90 days avoiding any complications," a statment on the club's official website read.
The Rossoneri also confirmed that Robinho strained his left thigh during the game at the Mestalla but that it will be a further two weeks before the full extent of the injury is ascertained.
The Brazil international, who recently signed a new deal with the San Siro outfit, scored the opener against los Che, after missing an earlier penalty.
