France have been dealt a blow after hooker Dimitri Szarzewski was ruled out of this week's clash with Ireland due to a thigh and shoulder injury.
The Racing Metro front-row forward sustained the problems during Saturday's victory over Grenoble and is replaced by Perpignan's Guilhem Guirado.
"We made this change because Dimitri, because of his injuries, will not be able to train before Thursday. His participation in the game would then be 50-50," said coach Philippe Saint-Andre.
"That's why we called up Guilhem so that he can train as of Monday with the group."
