Evra sent off before kick-off
The incident happened as Marseille players clashed with their own fans behind one of the goals at the Afonso Henriques stadium in Guimaraes during the warm-up for the game.
One video showed former Manchester United and Juventus player Evra climb over the advertising hoardings to talk to fans behind the goal.
A number of supporters jumped down from the seating area, leading to a scuffle with stewards and officials from the Ligue 1 side.
Other players climbed over the hoardings to join in the altercation.
Another video showed a Marseille player aiming a kick at the fans as the scuffling continued. Local media identified the player as Evra.
European soccer body UEFA said Evra had been given a red card without any further explanation.
Marseille said after the game that Evra had been sent off over “an altercation with supporters during the warm-up”, although it did not specifically mention the kick.
