The Serbian international winger pulled out of training on Wednesday with a worrying muscle problem.
The midfielder, signed last summer from CSKA Moscow, has undergone a series of tests which have confirmed a strain to his right thigh.
Meanwhile, new boy Mirko Vucinic did return to training on Friday after he recovered from flu-like symptoms.
Juventus were set to play Udinese on Sunday, but the Week 1 fixtures have now been postponed because of strike action.
