Neymar, one of the five players, fought a brawl after Paris Saint German lost to Marseille 1-0.
Layvin Kurzawa and Leandro Paredes were also shown the PSG red card, and Jordan Amabi and Dario Benedetto were given a march order to Marseille.
Neymar was sent off after colliding with Alvaro Gonzalez in close quarters.
When the Brazilian left the Parc des Princes pitch, he was seen telling a fourth employee that he had been racist.
Marseille’s boss André Villas-Boas could not confirm Neymar’s claim, but told the media that “racism is unacceptable in football.”

Benedetto and Paredes kickstarted the struggle as the Kurzawa-Amabie deal was hit and the stars on both sides quickly piled up.
After peace was restored and the cards were cleared, PSG played the rest of the match with eight men and nine Marseilles on the pitch.
Marseille star Florian Tuabin, who scored the only goal, ran into a turmoil and said, “Many children were watching tonight.
Meanwhile, PSG Sporting Director Leonardo accused the match’s official Jerome Blizzard: “I don’t know why there are no turpins or bouquets in games like this.
“This referee has no experience. It’s one Europa League match.”
All five players were sent off during the downtime, but the match itself was a fierce incident in which more than 36 fouls were committed.
A total of 12 yellow cards were also dealt.
Last year’s Champions League finalist Paris Saint-Germain has made a terrible start in League One this season and has lost both opening matches.
