Cannavaro and fellow defender
But those punishments were overturned on appeal last week and both players were unused substitutes for Napoli's 1-1 draw at Fiorentina.
Cannavaro finally returns to action at the Stadio Ennio Tardini, where he turned out for seven years, and is raring to go.
He told La Repubblica: "I left a lot of friends there and I have great memories of my time in Gialloblu. But it won't be easy for us.
"I really can't wait to play again. I've been training more than ever and I'm ready."
Recalling the day he heard the news of his ban, he added: "I was watching a film with my wife and kids, then at one point I changed the channel.
"Sky were announcing Napoli's punishment. I thought things had been looking good so I reacted to the news by bursting into tears.
"I suffered an injustice but Grava and I came out of it clean. There is no black mark on our careers and that is the important thing."
Juventus leads the current standings by five points but anything less than a win over Genoa on could allow Napoli and Lazio to close the gap.
"I hope we can keep attacking the top end of the table," Cannavaro added. "I realised Fiorentina were scared of us and that means we have become stronger.
"We will stay in Juventus' wake, ready to take advantage of any misstep by the Bianconeri."
Juve - which will sign
Lazio, meanwhile, held Juve to a creditable 1-1 draw in the first leg of the Coppa Italia semi-final and aims to keep pace with the Italian champion with a positive result over Chievo.
AC Milan continued its resurgence with a 2-1 victory over Bologna that took it above Roma and into sixth place, with a potential win at Atalanta promising fifth place should Fiorentina falter at eighth-placed Catania.
