Sami Khedira has been sidelined for two months with a thigh injury, Juventus have confirmed.

The midfielder has struggled with fitness and form for the last couple of seasons, culminating in him leaving Real Madrid for the Scudetto holders on a free transfer this summer after spending much of 2014-15 on the bench.

Khedira suffered the latest blow on Saturday when he was stretchered off in the first half of Juve's 2-0 defeat to Marseille, and Massimiliano Allegri had confirmed the he would at least miss the Supercoppa Italiana on August 8.

However, the Champions League runners-up have now confirmed the injury will see Khedira miss a lot more than just the clash between Juventus and Lazio this coming Saturday, ruling him out of the first seven Serie A matches of 2015-16.

"Sami Khedira will be sidelined for approximately two months after medical examinations revealed a second-grade myotendinous tear of the rectus femoris muscle in his right thigh," the Bianconeri said in a statement on their website on Monday.

"The German midfielder sustained the injury during Saturday's pre-season friendly against Olympique Marseille at the Stade Velodrome."
