Six Nations leaders France have kept faith with a majority of the side that thrashed England last week by making just one change to the starting line-up for Saturday's match against Wales.
Flanker Julien Bonnaire has been called into the team in place of Olivier Magne, who drops for the bench for the Millennium Stadium encounter.
Ireland must rely on France losing in Cardiff if they are to secure the title with both sides level in the standings on six points following three wins and a defeat apiece, although the French (+58) have a superior points scored advantage should both teams remain level.
Ireland (+30) travel to Twickenham on Saturday to face a revamped England side, knowing that a victory may still not be enough to lift the title. Scotland, who face Italy in Rome on Saturday, are level with England on four points, with Wales on three and Italy on one.
Two years ago, France defeated Wales 29-22 the last time the teams met in Cardiff, but the Welsh triumphed 24-18 in Paris last season.
