Fiorentina goalkeeper Sebastien Frey is set to miss the rest of the season after suffering a serious knee injury during training.
The 30-year-old Frenchman is set to be sidelined for at least four months, with a six-month lay-off a real possibility.
A statement on the club's official website confirmed: "ACF Fiorentina communicate that the diagnostic tests on Sebastien Frey have revealed a subtotal lesion on his anterior cruciate ligament.
"This means surgery is necessary to stabilise the knee and that will take place over the next few days. The prognosis for his complete return is between four and six months."
Frey has been with La Viola since the summer of 2005, having previously played in Serie A for Parma, Verona and Internazionale, having started his career in his homeland with Cannes.
The injury to Frey opens the door to summer signing Artur Boruc to stake his claim for a regular starting spot, the Pole having had to settle for a back-up role since his arrival from Celtic.
