Fiorentina attacker Stevan Jovetic is a major doubt for this weekend\'s Serie A encounter against AC Milan. The 22-year-old complained of pain in his adductor muscle following Montenegro\'s 1-0 defeat against the Czech Republic on Tuesday in the second leg of the Euro 2012 play-offs. Subsequent tests have shown that Jovetic is nursing a minor muscular problem in his hip, with the player having already begun treatment, according to the club\'s official website. Fiorentina have not announced how long the player will be out for, but it is understood that his involvement in Saturday\'s game is at risk. Fiorentina are currently 13th in the league standings, while Milan are third.
