Boosted by the recent arrival of Lionel Messi at Paris Saint-Germain, the French championship attracted attention for the wrong reasons on Sunday.
The league game between Nice and Marseille was abandoned when Marseille refused to resume the game for safety reasons.
“The safety of our players was not guaranteed,” said Marseille President Pablo Longoria.
The match was interrupted by players leaving the pitch after home supporters threw projectiles and invaded the pitch. Unverified photos on social media showed at least three players were injured.
When it was decided to resume play, Nice 1-0 ahead, Marseille refused to return to the field. Nice warmed up and the match had to resume with a Marseille corner. No visiting player was present to take the corner, the referee blew the whistle and the match was abandoned.
If the usual French league rules are applied, an automatic 3-0 victory will be awarded to Nice.
Nice supporters had already been warned against throwing objects by the stadium announcer when, about 15 minutes from the end, Marseille midfielder Dimitri Payet was hit in the back by a bottle thrown from an area with Nice supporters. Payet returned the bottle to the crowd, prompting a significant number of Nice supporters to rush onto the pitch.
Messi and his PSG teammates travel to Nice on March 6.
Angers and Clermont were the only teams other than PSG to have won their opening two matches, but they lost their first points of the season on Sunday.
Angers had not conceded a goal before Sékou Mara scored for Bordeaux in the 10th minute. But Romain Thomas equalized shortly before half-time and the match ended 1-1.
Substitute Elbasan Rashani scored twice in the final 10 minutes to help promoted Clermont defend after two goals behind and snatch a 3-3 draw at Lyon.
PSG won 4-2 in Brest on Friday.
Strasbourg and Troyes both collected their first points of the season in a 1-1 draw.
Lorient saw two players sent off late in a 3-1 loss to Montpellier, which recorded their first win of the season.
Rennes also won their first game with a 1-0 victory over Nantes, while Metz and Reims drew 1-1.
