Six Nations organisers say they will make a call regarding the meeting of France and Scotland on Wednesday.
The sides are due to meet on Sunday afternoon at the Stade de France, but the hosts have suffered an outbreak of COVID-19.
Nine of the matchday 23 that beat Ireland 15-13 at the Aviva have tested positive. In total, there have been fourteen positive cases, including head coach Fabien Galthie.
Six Nations organisers say if the game cannot go ahead on Sunday, then it will be re-fixed "for the earliest possible date".
France are still chasing a Grand Slam following wins over Ireland and Italy in their opening two weekends.
Six Nations statement:
A meeting of the Six Nations Testing Oversight Group (TOG) took place today to review the situation in France in relation to the COVID-19 outbreak in the French team.
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 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.
