Nice and Marseille have been summoned to a disciplinary hearing on Wednesday after their Ligue 1 match on Sunday had to be abandoned due to crowd trouble, the French professional league (LFP) said.
The match at Nice's Allianz Riviera was abandoned in the 75th minute after Marseille players clashed with home fans who pelted them with missiles and stormed onto the pitch.

French police said on Monday they will close the south stand of the stadium for the next four home matches.
In a statement, the prefect for the region that includes Nice also said that anti-projectile fencing would be installed in front of the stand as soon as possible.
Marseille midfielder Dimitri Payet was struck by a bottle thrown by Nice supporters as he was about to take a corner. After he hurled the bottle back at them, a full-scale brawl ensued when some of the fans rushed onto the field.
"Those fans should clearly never have been allowed to get onto the pitch," French Sports Minister Roxana Maracineanu told BFM TV, adding that the trouble was all the more regrettable given how sports venues had been empty for several months due to COVID-19 health protocols. "These incidents are an insult for sport and football."
The trouble was also condemned by Christian Estrosi, the mayor for the city of Nice.
"This violence is unacceptable. Sanctions must be taken by the French football league once they have found out who was responsible," Estrosi said.
The clashes tarnished the image of France's Ligue 1 just as the league was hoping to win more viewers across the world following the arrival of Argentina international Lionel Messi at Paris Saint-Germain.
Players from both Nice and Marseille retreated to the tunnel and play was held up for 90 minutes before referee Benoit Bastien declared the match abandoned. Nice players had returned to the pitch shortly before the match was called off but Marseille's line-up refused to join them.
Nice president Jean-Pierre Rivere had appealed for calm over the stadium's public address system during the delay but angry Marseille players and staff refused to carry on.
Marseille president Pablo Longoria said the club had decided not to continue with the match despite a decision by the football authorities that play should resume.
Revere partially blamed Payet and his teammate Alvaro Gonzalez for the chaos after they retaliated by hurling bottles back at Nice fans and accused Marseille staff of hitting some of the home players.
However, Benoit Payan -- the mayor for the city of Marseille -- backed his club's decision not to resume the match.
"Proud of my team for not being prepared to take part in this masquerade," Payan wrote on Twitter.
In a statement on Monday, Nice said: "any so-called supporters found guilty of involvement in these incidents deserve the harshest of penalities" and called for protective barriers to be installed around certain sections of the stadium.
The club also said that: "While nothing can excuse the actions of a few individuals guilty of throwing bottles onto the pitch, there is no doubt that it was the attitude and actions of several members of Olympique de Marseille that saw the incident escalate out of control."
