Fabio Cannavaro is set to miss Italy's Confederations Cup opener against USA on Monday.
The veteran defender is struggling with a calf problem and will not be risked against the Americans.
However, the Italy medical staff are confident the Juventus centre-half will be back in time for the Azzurri's remaining Group B fixtures against Egypt and Brazil.
He will be evaluated on a day-to-day basis, but the World Cup-winning skipper is not expected to be sidelined for a prolonged period of time.
While the news on Cannavaro has come as a blow to Marcelo Lippi's side, there are also concerns regarding the fitness of his Stadio Olimpico team-mate Nicola Legrottaglie.
The commanding defender could still come into contention for the clash against USA, but he is carrying a muscular injury which will require treatment.
