French police say they will close the south stand at Nice soccer club's Allianz Riviera stadium for the next four home matches after crowd trouble at a Ligue 1 game on Sunday.
They also said anti-projectile fencing would be installed in front of the stand as soon as possible.
Nice and Olympique de Marseille have been summoned to a Ligue 1 disciplinary hearing on Wednesday after their match had to be abandoned due to crowd trouble.
The game at Allianz Riviera was called off in the 75th minute after Marseille players clashed with home fans who pelted them with missiles and stormed onto the pitch.
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.
"These incidents are an insult for sport and football."
A judicial probe is under way into Sunday's trouble, added local French media reports.
French prosecutors on Monday opened several investigations on counts relating to objects being thrown, the use of furniture as projectiles and aggravated voluntary violence.
Such acts are punishable by a maximum of three years in prison, fines and a ban on entering sports arenas for five years.
Prosecutors said video surveillance would be examined to identify those involved.
The clashes marred the image of France's top-flight just as the league was hoping to win more viewers across the world following the arrival of Argentina great Lionel Messi at Paris St Germain.
Players from 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 team 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 soccer authorities that play should resume.
Revere partially blamed Payet and his teammate Alvaro Gonzales for the chaos after they retaliated by hurling bottles back at Nice fans and accused Marseille staff of hitting some of the home players.
