Evra was engaged in a heated exchange with a group of fans from an area reserved for Marseille supporters in Portugal before aiming a head-high kick at one of them, an reporter observed.
Stewards at the ground quickly intervened to break up the trouble, with Evra, who was originally listed as a substitute, ordered to return to the dressing room by the referee.
The 36-year-old former Manchester United defender has received heavy criticism for his performances this season and lost his place in the team to on-loan Aston Villa left-back Jordan Amavi.
