Kylian Mbappe was missing from group training on Tuesday as France prepared for their World Cup quarter-final against England, the French football federation said.
"Kylian Mbappe is working in the recovery room, it is usual two days after a game," the FFF said.
Mbappe, 23, scored twice as the defending champions beat Poland 3-1 in the last 16, taking his tally to five goals in Qatar and nine overall at the World Cup.
