Neymar was among five players sent off as a huge brawl marred Paris Saint-Germain's 1-0 defeat by Marseille.
Layvin Kurzawa and Leandro Paredes were also shown red cards for PSG while Jordan Amavi and Dario Benedetto were given their marching orders for Marseille.
Neymar was sent off for lashing out at Alvaro Gonzalez in the melee.
As the Brazilian left the pitch at the Parc des Princes he was seen telling the fourth official that he had been subjected to racism.
Marseille boss Andre Villas-Boas was unable to confirm Neymar's claim but told the press: "racism is unacceptable in football."
Benedetto and Paredes kick-started the tussle as stars from both sides quickly piled in, with Kurzawa and Amavi trading blows.
After peace was restored and cards put away, PSG played the remainder of the match with eight men on the pitch and Marseille nine.
After the game Marseille star Florian Thuavin, who scored the only goal, hit out at the ruckus, saying: "A lot of children were watching tonight, we all have to be examples."
Meanwhile, PSG Sporting Director Leonardo slammed the match official Jerome Brisard, adding: "I don't understand why for a match like this we don't have Turpin or Bouquet.
"This referee has no experience, one Europa League match."
All five players were sent off in stoppage time, but the match itself was a fiery affair with no fewer than 36 fouls committed.
A total of 12 yellow cards were also handed out.
Last year's Champions League finalists Paris Saint-Germain have got off to a terrible start in Ligue 1 this season, losing both of their opening matches.
On Thursday the Ligue 1 champions were beaten 1-0 by Lens.
This Sunday they were again beaten 1-0, failing to score in either of their opening games for the first time since the 1978/79 season.
