A decision on whether to proceed with France's home Six Nations clash with Scotland will be made on Wednesday night.
The fixture is due to take place at Stade de France on Sunday, but Les Bleus currently have 14 positive Covid cases in their camp.
Head coach Fabien Galthie and world-class scrum-half Antoine Dupont were among those who contracted the coronavirus last week, but three players were confirmed as positive cases on Sunday and a further five this morning, with two backroom team members also self-isolating as "suspected cases".
Five players have been called into the squad and the French plan to train again on Wednesday and team manager Raphael Ibanez expressed confidence that the game would go ahead.
However a meeting of the Six Nations Testing Oversight Group (TOG) took place today to review the situation.
A statement released afterwards read: "The TOG was advised by the French Rugby Union representative that all players who returned to the National Training Centre yesterday were tested on arrival and put in isolation pending results.
"All five players (including captain Charles Ollivon) who tested positive have now left the training base.
"The rest of the squad, all of whom tested negative are training with restricted movement and no close contact for the next 48 hours. All players and staff will be tested every 24 hours.
"The TOG will reconvene on Wednesday 24 February in the evening to review the situation. A decision on whether the France v Scotland fixture can go ahead will be made at that stage.
"Ensuring the health and safety of all players and staff is our number one priority. Should the decision be that the fixture cannot go ahead, the match will be rescheduled for the earliest possible date.
"Six Nations would like to wish all affected players, coaches, and support team a speedy recovery".
