Lyon midfielder Ederson took part in training on Tuesday for the first time since rupturing a hamstring in August.
The 25-year-old Brazilian trained with a small group of team-mates, with much of the squad away on international duty.
Ederson was injured making his Brazil debut in a match against the United States. Prior to the injury, he had been a virtual ever-present for Lyon since joining from Nice in 2008.
Lyon have still not announced when they expect him to make a return to the side.
