The 36-year-old's injury is not as serious as first thought and there was also good news regarding Mattia De Sciglio, Daniele De Rossi and Andrea Barzagli
The veteran goalkeeper sat out his country's 2-1 victory over England in Manaus last Saturday due to an ankle injury but Italy's team doctor Enrico Castellacci confirmed on Monday that he was hopeful Buffon would not miss any further games in Brazil.
And the 36-year-old now appears to be in line for a return in Recife on Friday, with Mattia De Sciglio, Daniele De Rossi and Andrea Barzagli also playing some part in Tuesday's session.
"Good news for Cesare Prandelli," the FIGC announced on its official website. "Buffon, De Sciglio, De Rossi and Barzagli returned from injury and are on the road to recovery."
With all four players available to coach Cesare Prandelli, Italy were able to train together as a full squad for the first time since Buffon suffered his injury last Friday.
“Right after the injury on Friday evening, [Buffon] thought he had to leave the World Cup, but now as time passes he knows that this isn’t the case,” said Castellacci.
"Yesterday he wasn’t able to play, he is in therapy and today we’ll do other checks and if necessary, other diagnostic tests. We will try to recover him as soon as possible even if his health is priority."
Prandelli, though, may choose to leave the veteran out in order for him to make a full recovery as Italy have one eye on the knockout stages.
