Marseille's Ligue 1 clash with champions Paris Saint-Germain was called off on Sunday afternoon after severe weather warnings in the south of France.
The match was scheduled to start at 845pm on Sunday at the Vélodrome in Marseille city centre.
But during the afternoon, police chiefs in the Bouches-du-Rhône department – the region in which Marseille is situated – said there was a significant risk of flooding in and around the 65,000-seat stadium.
The Ligue de Football Professionnel, which runs the top two professional divisions in France, said the match would be played at 8pm on Monday night.
The game, nicknamed Le Classique, as a nod to the rivalry between the clubs and the cities, is one of the highlights of the top flight calendar.
The fifth game of the 2025/2026 season will give Marseille the chance to arrest PSG's perfect start to the campaign.
Luis Enrique's charges have won all four of their games to sit top of Ligue 1 with 12 points.
Marseille lie seventh with six points following two wins and two losses.
It will take place as a host of star players and coaches gather in Paris for the Ballon d"or awards ceremony.
Nine PSG players are among the list of nominees for the sport's most prestigious individual award.
Enrique is also nominated for leading PSG to a domestic treble of Ligue 1 title, Coupe de France and French Super Cup as well as the Champions League crown.
