Lyon president Jean-Michel Aulas admits he is "worried" after Bafetimbi Gomis fainted yet again while on international duty.
Gomis collapsed during training with the France squad on Wednesday but regained consciousness a minute later and rejoined his team-mates after a quarter of an hour.
It is the third time the 24-year-old has fainted since joining Lyon in the summer and the second in the space of a week, and Aulas admits it is a concern.
"We can't not be worried, it scares you each time," Aulas told ITele. "A vasovagal episode (fainting) is part of the things that can happen to people who have this type of constitution.
"It's now three times that it's happened. Yes, I'm worried."
