AC Milan lose Giacomo Bonaventura, Mattia De Sciglio to injury

MILAN -- Already struggling in recent weeks, AC Milan have lost key starters Giacomo Bonaventura and Mattia De Sciglio to injury.

Bonaventura, a midfielder, was diagnosed with a tear to his left thigh muscle and will require surgery. He will likely miss three months.

De Sciglio, a full-back, damaged ligaments in his right ankle in a 2-1 loss at Udinese on Sunday and could be out until March.

He sent a message via Twitter to thank his fans for their support, saying that he promised "to return soon."

Milan have won just one of their last six Serie A matches and fallen from the Champions League spots to seventh place, 14 points behind leaders Juventus.

The Rossoneri were also eliminated from the Italian Cup by Juventus last week.
