Marco Storari will start in his absence, with Conte hailing the 36-year-old as a worthy stand-in.
"Storari will be in goal," Conte told reporters. "Gigi was suffering with illness after the Inter game and it popped up again after Bayern.
"Behind him here is a great goalkeeper who would be first-choice in any other Serie A side.
"If I didn't have the guarantee of a player like Storari, then I'd ask Gigi to make a sacrifice."
Juventus are currently nine points clear at the top of Serie A.
