French football was again marred by violence after Olympique de Marseille's Ligue 1 match against Olympique Lyonnais was called off on Sunday when the visitors' bus and some fans were pelted with stones and beer bottles, injuring Lyon coach Fabio Grosso.
Grosso, a World Cup winner with Italy in 2006, sustained facial injuries during the incident, leaving league officials to deal with another episode of rioting fans.
Since Sunday's incidents happened outside Marseille's Stade Velodrome, the French League (LFP) have no jurisdiction to impose points deductions, although it could decide that the game has to be played behind closed doors.
Interior minister Gerald Darmanin said nine people had been detained so far. "I hope the highest possible prison sentences will be handed to those fans that ruined the party for everyone," he added on BFM TV.
The incidents are a bad look for the LFP, who have been negotiating a TV rights deal for 2024-29, with the tender ending on Thursday, and made for embarrassing footage less than a year before the 2024 Paris Olympics.
Some preliminary round Olympic matches will be played in Marseille, where violence erupted at the 1998 World Cup between England fans and French police.

"OL regrets that this type of situation recurs every year in Marseille and calls on the authorities to assess the seriousness and repetition of this type of incident before an even more serious tragedy occurs," Lyon said in a statement, with the club adding they would lodge a formal legal complaint.
"What happened to Fabio Grosso is totally unacceptable," OM president Pablo Longoria said.
"This is something that cannot happen in football. Even if it happened outside of the stadium, it is unacceptable. I am angry and appalled by the situation."
Marseille condemned the behaviour of their fans in a statement on Monday.
"Olympique de Marseille deplores the unacceptable incidents that took place in the vicinity of the Stade Orange Velodrome, involving the professional team bus and buses of Olympique Lyonnais supporters," the statement read.
"The club wishes Lyon coach Fabio Grosso a speedy recovery and strongly condemns this violent behaviour, which has no place in the world of football or in society."
"We have seen just about everything you would not want to see," sports minister Amelie Oudea-Castera told France 2 TV, adding that fans had also been chanting homophobic and racist slurs inside Marseille's Stade Velodrome. "It was distressing, revolting, disgusting."
Lyon condemned their fans' behaviour after some were seen making Nazi salutes at the Velodrome.
"OL firmly condemns the unacceptable racist behaviour of individuals in the stands on Sunday," the club said in a statement.
"The club has requested the footage in order to identify the perpetrators of any act contrary to the law, but also contrary to its values, and reiterates its determination to keep them away from the stands."
Sunday was not the first time that the away team bus has been targeted in Marseille, with previous incidents reported in 2016 and 2019.
It also came after fan trouble marred the 2021-2022 season. That time Nice were docked two points, one of which was suspended, after serious incidents during their game against Marseille when visiting players clashed with home fans who pelted them with missiles and stormed on to the pitch.
The northern derby between RC Lens and Lille was also hit by crowd problems, with the start of the second half delayed after rival fans threw objects at each other before people ran on to the pitch, prompting riot police and stewards to intervene.
