MILAN, Nov 27 (Reuters) - AC Milan midfielder Giacomo Bonaventura will be out of action for the rest of the season after having surgery on his left knee, the Serie A club said on Tuesday.
Milan said that Bonaventura underwent a cartilage repair procedure in Pittsburgh in the United States. “(It) was successful and the recovery time is estimated in eight to nine months,” the club said in a statement.
The 29-year-old has been a regular for Milan since joining them from Atalanta in 2014, scoring three goals in eight outings this season, and has also made 14 appearances for Italy.
The knee suffered an inflammation after the 1-0 defeat to neighbours Inter Milan in October.
Milan are suffering what coach Gennaro Gattuso has described as an emergency with a number of players out through injury.
They include Croatia fullback Ivan Strinic, defenders Alessio Romagnoli, Mateo Musacchio and Mattia Caldara and midfielder Lucas Biglia. (Writing by Brian Homewood Editing by Toby Davis)
