The French football league’s disciplinary watchdogs said the match – which was abandoned when Nice were leading 1-0 – will have to be replayed on a neutral ground and without spectators.
Sébastien Deneux, president of the disciplinary commission at the Ligue de Football Professionel said: “What was important for us was the seriousness of the incidents. The best and fairest decision was to replay the match.”
Nice, who were told they would be docked another point if there were any further crowd problems, will drop to fifth after the sanction.
Marseille’s Dimitri Payet was given a suspended one-match ban for hurling a bottle back into the crowd after one hit him in the back as he prepared to take a corner.
