TURIN, Italy -- Juventus midfielder Roberto Pereyra will be sidelined for more than a month with a muscular problem, and teammate Kwadwo Asamoah has had another injury setback.
Pereyra went off in the 37th minute of Juventus' 2-0 win over Atalanta after pulling up clutching his hamstring and the team say tests "revealed a second-grade tear" in his right thigh.

Juventus say the Argentina midfielder will be out for about 40 days.
Asamoah -- who replaced Pereyra on Sunday -- will likely return to action in 20 days following "a first-grade tear" in his left thigh.
Asamoah missed most of last season with knee problems and had only made one appearance this season prior to Sunday's win.
"During the match, El Tucumano [Pereyra] suffered a muscular problem in his right thigh," a statement on the Bianconeri website said.
"Diagnostic tests carried out this morning showed a second-degree injury to semimembranosus muscle, with the recovery time needed estimated to be 40 days.
"The Ghanaian midfielder [Asamoah] also suffered a muscular problem, a first-degree injury to the biceps femoris of the left thigh, so the prognosis for recovery is 20 days."
