But following a heavy defeat to Wales in round three, Machenaud donned the No.9 jersey for Les Bleus' final two games, helping them to victory over Scotland before narrowly losing to eventual RBS 6 Nations champions Ireland.
Machenaud could be straight back to action again this weekend in the Top 14 as Racing Metro take on Grenoble.
And with Racing currently sat seventh, Machenaud is more than happy to keep putting in the hard graft.
"I am happy to see my friends and now be back with Racing, we are pretty much in the final games of the season, so you have to throw yourself back in," he said.
"We have two very important matches, at Grenoble and then home to Stade Francais and then after that I will have a week's holiday to recuperate.
"But if we win at Grenoble and get another away victory at some point, and win all our home matches we can make the play-offs."
