Lyon attacking midfielder Mathieu Valbuena was reportedly assaulted after the club's 1-1 draw with Marseille on Sunday.
The 30-year-old returned to the Velodrome for the first time after leaving the club in 2014 and was targeted by Marseille fans during the game, leading to play being suspended for over 20 minutes.
According to Mediafoot Marseille, two Marseille youths attacked Valbuena as he left the team bus at the airport and it is believed that a friend of the French international following behind managed to defuse the situation.
Valbuena has made five appearances for Lyon since joining the club from Dynamo Moscow in the summer.
