Jauzion, France's leading centre, missed the first three RBS 6 Nations Championship games as he recovered from a hand injury suffered on club duty before the tournament began.
The 29-year-old will return to the Test arena on Sunday when the French take on Italy in Paris, his first international since the World Cup semi-final defeat to England in October.
Much has changed in the Les Bleus camp since then, notably Marc Lievremont replacing Bernard Laporte as head coach.
And a new, youthful squad has been ordered to play with a bold, attacking outlook that is light years away from the more conservative philosophy adopted by Laporte.
Jauzion admits he felt like he had gatecrashed a kindergarten party when he made his return to Marcoussis, the French squad's training base in the south of Paris, last week.
And he is still coming to terms with what is expected under the new staff.
"It is funny," said the Toulouse midfielder, who has 50 caps to his name.
"I was never selected in the youth teams but here it feels like I am with a bunch of newcomers.
"It is good though. There is a lot of enthusiasm, a lot of desire and it is great to be part of it. It's great to be back at Marcoussis and there is so much to see because it is a new France team.
"We are playing another style of rugby, different to that of the previous staff, and it isn't easy to put in place, especially as all the players are not used to doing it at their clubs.
"But I believe it will come."
Jauzion, a permanent fixture in the France team when fit, has had a host of partners in midfield over the past few years.
He has lined up alongside Damien Traille, Florian Fritz and David Marty for the majority, but he will be part of a new centre combination this weekend.
Yann David, a 19-year-old who plays for Bourgoin, will be on Jauzion's shoulder and he is being tipped for big things.
David is yet another youngster being blooded by Lievremont, and Jauzion is impressed with what he has seen so far.
"He is someone who does not ask himself too many questions, who plays without a complex, who is conscious of his own qualities," added Jauzion.
"As well as his athletic qualities, he is someone who talks a lot and I think he is going to keep things simple. He has confidence.
"You will see what he can do."
David has not hidden his admiration for Jauzion.
"I love this player," he enthused.
"I am going to start next to Yannick Jauzion and that can only reassure me.
"Having seen that Damien Traille is also in the squad, I wasn't at all expecting to be named from the start. So it's great."
David, the son of two athletes - his father threw the discus and his mother the javelin, is a pocket battleship whose physique and style of play is comparable to Fritz.
"He is an excellent player, a puncher with a lot of power," said Lievremont, whose side struggled to penetrate a strong England defence in the 24-13 defeat to the 2003 world champions a week and a half ago.
