Sami Khedira leaves Juventus' friendly against Olympique Marseille with hamstring injury

It looks as though we have another injury to worry about, boys and girls.

Juventus midfielder Sami Khedira had to leave Saturday's friendly against Olympique Marseille after just 25 minutes thanks to a hamstring injury he picked up while sprinting back on defense. Khedira, who was signed on a free transfer from Real Madrid this summer, grabbed at his right hamstring moments after stretching out his leg trying to stop a pass from a Marseille player and subsequently falling to the ground in a heap of pain.

Khedira was visibly upset as he was loaded onto a stretched and carried off the field.

I'd be frustrated, too, if I were him. Or maybe it's more than that.

Khedira will certainly undergo tests in the next day or two to evaluate the severity of the injury. Speculating about injuries can drive you absolutely bonkers at times, but by the first impression of how Khedira reacted to it in the minutes after his hamstring went twang, his status for next weekend's Italian Super Cup against Lazio in Beijing is definitely up in the air. And if that's the case, he will join Andrea Barzagli and Giorgio Chiellini — both of which have picked up thigh injuries in the past week — on the injury list heading into the Supercoppa and the beginning of the 2015-16 Serie A season.

Of course, with Arturo Vidal now wearing the all-red Bayern Munich kit, Khedira's importance in the starting lineup is an obvious one. Could this injury open the door for somebody like Stefano Sturaro? That's who came on for him in the first half against Marseille, so it's possible. And if Max Allegri prefers to use Roberto Pereyra as a No. 10 right now, then Sturaro will certainly step into Khedira's place alongside Claudio Marchisio and Paul Pogba in the center of the midfield.

But I guess this is all speculation at this point. Once the actual medical tests happen and there's something posted on Juventus' website about it, we just have to sit around and wait. Hopefully Khedira's absence isn't all that much longer than the time it takes to hear about what happened to his hamstring.
