Milan may be without Antonio Nocerino and Mathieu Flamini for the match against Barcelona tomorrow.
The midfield pair have missed today's training session after coming down with slight muscle issues, according to reports.
The Rossoneri are already missing cup-tied Mario Balotelli, and could have to make do without the central duo.
Fitness tests will be done tomorrow to determine whether Nocerino and Flamini can play against the Blaugrana.
