Fourth-placed Marseille and Nice, who occupy eighth spot, were due to return to action at Stade Velodrome this weekend following the international break.
The fixture will instead be staged later in the season due to a COVID-19 outbreak at the club from the Cote d'Azur.
A statement released by Ligue 1 on Tuesday said: "Following the advice of the National COVID FFF Commission, which noted the unavailability of more than ten players on OGC Nice's 30-man squad list - due to positive RT-PCR tests - for the Round 11 Ligue 1 match against Olympique de Marseille, the LFP's Competitions Commission, acting under article 2. 4.2.2 of the protocol for the organisation of matches for the 2020-21 season, has decided to postpone the match, initially scheduled for Saturday 21 November 2020 at 21:00, to a date yet to be determined."
Meanwhile, the French Football Federation (FFF) has postponed the eighth round and last-32 Coupe de France matches due to be staged next month and in January due to the pandemic.
The decision came following the suspension of amateur competitions on October 29 and the FFF is working with regional leagues to come up with alternative dates for the ties to be played.
