This is just eight days after the team played the Champions League final against Bayern Munich (0-1 loss).
PSG announced already on Monday that two players in the squad had shown corona symptoms.
"All players and leaders will continue to be tested in the coming days," PSG said in a press release.
The French league's infection control protocol states that a club may not conduct training if the team has more than four players who have tested positive for the coronavirus.
Which players it is about is not official, but according to French L'Equipe, it is about the Argentines Angel Di Maria and Leandro Paredes, who both vacationed in Ibiza after the CL final, and the Brazilian star Neymar.
The French league started already at the end of August, but due to PSG's final game in the Champions League, the team will not start its league game until 10 September.
PSG's squad includes two French national team players, among them attacking star Kylian Mbappé, who have been selected for the Nations League match against Sweden on Saturday.
