MILAN, Sept. 30 (Xinhua) -- AC Milan striker Stephan El Shaarawy has been ruled out of Milan's Europe Champions League game against Ajax as he picked up an injury in training on Monday.

The Italian had been named in the squad for the Champions League tie after recently returning to action following a muscle strain.

However, the 20-year-old Italian international has reportedly suffered a metatarsal hairline fracture to his left foot, and is expected to be out of action for at least 15 days.

He thus will for sure miss the tie against Juventus at the weekend.
