France will be without wing Vincent Rattez for their Six Nations game against Wales in Cardiff on Saturday, 22 February.
The 27-year-old suffered a broken fibula as France beat Italy 35-22 to go top of the table on Sunday. He will miss the rest of the tournament.
The La Rochelle player came off in the closing moments at Stade de France, leaving France with 14 men.
Rattez later confirmed the fracture via social media.
