Fiorentina midfielder Riccardo Montolivo has been ruled out for up to six weeks after undergoing ankle surgery.
The 25-year-old Italy international travelled to Amsterdam for an operation to remove a bone fragment from his ankle and will now return to the club to begin his rehabilitation.
Meanwhile, goalkeeper Sebastien Frey has undergone surgery on the serious knee problem that will sideline him until the spring.
The 30-year-old French international damaged an anterior cruciate ligament in training last week and is set for five months out of action.
A statement on the club’s official website said: “Fiorentina announces that Sebastien Frey has undergone an operation for anterior cruciate ligament reconstruction performed by Professor Cerulli.
“The player will be discharged from the hospital tomorrow to start rehabilitation in Florence.”
