Juventus have confirmed a thigh muscle injury for Mirko Vucinic, while Stephan Lichtsteiner will need more tests.
The international pair both picked up problems during the 2-2 Champions League draw with Galatasaray on Wednesday.
Vucinic has been diagnosed with a first-grade tear to the femoral bicep of the left thigh. The club made no comment about how long he would be sidelined for, but this type of injury generally requires between one and three weeks.
Lichtsteiner, meanwhile, will be examined again on Friday after he reported an issue in the rectus femoris muscle of the right thigh.
Juventus will entertain Milan on Sunday.
