Kingsley Coman (26) has left France's training session on Thursday, two days before the defending champions face Denmark in Group D of the World Cup in Qatar.
The forward walked off the pitch with no apparent injury in a session that was attended by all players, including Raphael Varane who missed the opening 4-1 win against Australia after failing to fully recover from a hamstring injury.
Coman felt some muscle pain in a friendly match against a local team on Wednesday, Reuters understands.
Didier Deschamps's team have been hit by injuries, with forward Karim Benzema being ruled out last Saturday and full-back Lucas Hernandez leaving the tournament after sustaining a serious knee injury against Australia.
France lead Group D on three points, two ahead of Denmark and Tunisia.
