AC Milan and Italy forward Mario Balotelli will be sidelined for approximately ten days with a shoulder injury.
Medical tests on Thursday revealed Balotelli has damaged his acromioclavicular joint.
Balotelli went off clutching his shoulder 12 minutes from the end of Milan's 1-0 defeat at home to Atletico Madrid in the first leg of their Champions League last-16 tie.
Mattia De Sciglio was also forced off injured following a poor Emiliano Insua tackle in the first half. The Milan defender has a sprained and bruised ankle and will undergo more tests.
Milan visit Sampdoria on Sunday.
