France players Raphael Varane, Ibrahima Konate, and Kingsley Coman were absent from training on Friday due to cold-like symptoms, according to a source close to the team.
Coman, the Bayern Munich winger, had already missed a training session on Thursday due to a "light viral syndrome," according to the French Football Federation (FFF).
Coman was an unused substitute in the 2-0 win against Morocco in Wednesday's semi-final.
Varane and Konate's health will be a source of concern for France coach Didier Deschamps, as they formed the central defensive partnership against Morocco.
Konate had replaced Dayot Upamecano in defence for the semi-final after he was ruled out by illness.
Adrien Rabiot, who has played a key role in France’s midfield in Qatar, was also sidelined with illness for the semi-final.
France forward Randal Kolo Muani said in a press conference on Friday: “There is little bit of flu going around but nothing serious.”
