Fiorentina have been dealt a blow after they learned striker Stevan Jovetic will miss the majority of the season.
Jovetic sustained knee ligament damage on Tuesday following a collision with team-mate Mario Bolatti and is expected to be out for up to seven months.
The 20-year-old is expected to return in February or March and will undergo surgery in an attempt to clear up the problem.
The news will be a setback for Viola, who have had the talented Montenegrin as an almost ever-present fixture in their starting XI since his move from Partizan Belgrade in 2008.
A statement on the club's official website read: "Fiorentina announce that Stevan Jovetic has suffered a tear to the anterior cruciate ligament and the external collateral ligament of the knee.
"The footballer needs a surgical operation which will be planned in the next few days.
"It is foreseen it will take between six and seven months for his return to complete competitive activity."
