Forward set for spell on sidelines...
La Gazzetta dello Sport claimed he was screaming and in tears as medical staff rushed on the pitch following the clash.
A Fiorentina statement on their official website reads "ACF Fiorentina communicates that Stevan Jovetic has suffered a lesion to his cruciate ligament in his right knee.
"Surgery for the player is neccessary and that will be planned over the next few days. The times for his complete return are estimated between six and seven months."
It's a bad start for the Viola who were aiming high ahead of the new campaign with European football as their objective, but Jovetic's absence will severely deplete the squad.
