France coach Philippe Saint-André has added four players to his squad including teenage Toulouse centre Gael Fickou ahead of Saturday's Test against Samoa.
Toulouse centre Fickou, Racing Metro full-back/wing Benjamin Fall, Toulon flank Pierrick Gunther and Perpignan lock Sébastien Vahaamahina have joined the 27-man squad to prepare for the match at the Stade de France outside Paris.
Saint-André is considering freshening up his side after the 39-22 victory over Argentina which followed the 33-6 rout of Australia.
"They'll be with us until Tuesday and we'll take a decision on Tuesday evening," said Saint-André.
"I spoke with Marc Lièvremont and other former coaches and there's often been a few problems with rehabilitation and freshness in this third week of matches."
France will name their matchday 22 on Thursday.
