The Ligue 1 derby between Nice and Marseille was suspended on Wednesday following homophobic chants from a section of the fans.
Players from both teams were escorted from the pitch midway through the first half of the contest following repeated appeals to stop the chanting.
The game, which was 0-0 at the time, resumed after a 10-minute delay.
Referees in France have been instructed to stop matches if homophobic songs are heard.
There were also reports of homophobic banners in the stands.
This was Nice's first game since they were bought by Ineos, the chemical company founded by British billionaire Sir Jim Ratcliffe.
