The Italy international could miss the Rossoneri's upcoming Serie A clash with Juventus because of a problem sustained in Wednesday's Champions League loss to Atletico Madrid
AC Milan have been rocked by the news that star striker Mario Balotelli will be out of action for around 10 days after injuring his shoulder in the 1-0 Champions League defeat to Atletico Madrid on Wednesday.
The Italy international was substituted in the second half of the first leg of the Rossoneri's last-16 tie with Atleti after falling awkwardly as Clarence Seedorf's side fell to a narrow defeat at the San Siro.
The Rossoneri have confirmed that the former Manchester City forward will miss Sunday's Serie A trip to Sampdoria on Sunday, and faces a race against time to be fit to face leaders Juventus seven days later.
A club statement released on Thursday read: "AC Milan wishes to communicate that in yesterday evening's match [against Atletico], Mario Balotelli suffered a shoulder injury.
"The player visited with professor Alessandro Castagna today [Thursday] and the recovery time has been estimated at around 10 days without unforeseen complications.
"Mattia De Sciglio also suffered an ankle injury in yesterday’s match and the player's recovery time will be decided on in the coming days based on medical tests."
