Unbeaten France have made two changes to their squad for Friday's game against Wales in Cardiff.
Racing Metro flanker Wenceslas Lauret and Castres hooker Brice Mach come in for the Millennium Stadium clash.
Mach takes over from Clermont Auvergne's Benjamin Kayser (knee) while coach Philippe Saint-Andre has opted for Lauret instead of a prop.
Bernard Le Roux (concussion) and Luc Ducalcon (knee) were ruled out of front-row contention.
Five-times capped Lauret is one of four Racing Metro players who could face Welsh club-mates Jamie Roberts, Dan Lydiate and Mike Phillips.
Backs Maxime Machenaud and Marc Andreu and hooker Dimitri Szarzewski are also in coach Philippe Saint-Andre's squad.
France beat England 26-24 in their Six Nations opener and a week later saw off Italy 30-10, with both wins coming at Stade de France.
Skipper Sam Warburton has said France cannot rely on the Six Nations history that has seen them win the title in the seasons following the last four British and Irish Lions tours.
Injury prevented Lauret taking part in France's two opening wins, but the 24-year-old was back for Racing-Metro's 18-8 Top 14 win over Bayonne, in which Phillips went on as a last-quarter replacement.
Ducalcon, capped 17 times, initially took over from banned prop Rabah Slimani, who is out for two weeks after being sent off for a headbutting incident in their win over Italy.
However, Saint-Andre brought in Lauret instead of a prop in the wake of Bernard Le Roux being diagnosed with concussion suffered at the end of the Italy game.
