Serie A leaders Juventus will have to make do without Montenegro forward Mirko Vucinic for the rest of the year, the club said on Tuesday. The 28-year-old pulled a hamstring during Sunday\'s 2-0 win over Cesena and is expected to be out for three weeks. It means he will miss league matches against Roma, Novara and high-flying Udinese, as well as Thursday\'s Italian Cup clash with Bologna. Vucinic has proved a great success since his summer move from Roma and has teamed up well with fellow forwards Alessandro Matri and Simone Pepe, helping Juve remain unbeaten in the league and go two points clear at the top.
