Juventus midfielder Mohamed Sissoko will be sidelined for almost a month through injury.
Sissoko sustained a muscular problem in his left thigh during Wednesday's 5-1 win over Sampdoria.
A statement from Juventus read: "The tests done on Sissoko have confirmed a strained muscle in his left thigh and he will only be able to return to play in about 25 days."
Sissoko will miss the Serie A games against Napoli, Atalanta and Udinese as well as next week's UEFA Champions League match at Maccabi Haifa.
However, the 24-year-old could recover in time for the European encounter at Bordeaux on 25 November.
