Milan defender Theo Hernandez left the training session with France after only 20 minutes after a knee injury.
France are preparing for their Euro 2024 opener against Austria on Sunday.
They then play the Netherlands on June 21 and Poland on June 25.
Hernadez was expected to be in the starting line-up, but his appearance has been questioned after he left training on Thursday after just 20 minutes.
He was injured in France's goalless draw against Canada.
The 26-year-old has 27 appearances for France.
He scored two goals and assisted eight times.
He was in the team that lost in the final of the World Cup "Qatar 2022" to Argentina on penalties.
