Five more France rugby players have tested positive for Covid-19, bringing the number of infected players to 10, with Six Nations officials set to meet on Wednesday to decide if the team's match with Scotland on Sunday can go ahead as planned.
Cyril Baille, Peato Mauvaka, Romain Taofifenua, captain Charles Ollivon and Brice Dulin were the players who returned positive tests in the latest round of testing on Sunday.
Two members of staff are also suspected to have contracted the virus.
Les Bleus' last game was a 15-13 win over Ireland in Dublin eight days ago.
Centre Arthur Vincent, hooker Julien Marchand, wing Gabin Villiere, prop Mohamed Haouas and scrum-half Antoine Dupont had tested positive last week, along with coach Fabien Galthie and three other staff members.
The players who tested positive have been replaced in the 31-man squad, with the team set to return to training on Wednesday, the FFR said in a statement.
France are scheduled to play Scotland at the Stade de France in Paris on 28 February.
Les Bleus lead the standings with two wins from two games, ahead of Wales on points difference.
Six Nations officials said over the weekend they were confident the game in Paris would go ahead.
But organisers said on Monday their Testing Oversight Group reviewed the situation and would reconvene on Wednesday.
"Should the decision be that the fixture cannot go ahead, the match will be rescheduled for the earliest possible date," organisers said in a statement.
"Ensuring the health and safety of all players and staff is our number one priority."
Hooker Gaëtan Barlot (uncapped, Castres Olympique), prop Thierry Paiva (uncapped, Bordeaux Bègles), lock Cyril Cazeaux (uncapped, Bordeaux Bègles), back row Baptiste Pesenti (2 caps, Pau) and full-back Thomas Ramos (14 caps, Stade Toulousain) have been called up to replace those affected.
"With regards to isolating those players and coaching staff concerned are returning home at the moment," the FFR added in their statement.
"The return to training for those remaining is still planned for Wednesday but conditional on the results of the tests carried out every 24 hours."
