Juve duo Gianluigi Buffon and Mauro Camoranesi have picked up muscle injuries in training and will be unavailable for Italy's matches in Bulgaria on Saturday and at home to Montenegro the following Wednesday.
The pair will be out for a month and 15-20 days respectively, doctors said Tuesday.
Buffon has just come back from a two-week stop, playing in Juve's 2-1 home defeat to Palermo.
