Juventus will have to do without Emanuele Giaccherini for the next three weeks after he sustained another injury.
The former Cesena left-sided winger had made his comeback from a long lay-off as a substitute in Sunday's 0-0 draw at Chievo.
However, he lasted only a few minutes before limping off again with a new setback.
The official Juventus website confirmed Giaccherini has suffered a first degree thigh strain in his left leg.
Medical staff predict he will be out of action for around 20 days.
The Bianconeri hope to have him back for the trip to Napoli or the home game with Palermo.
