Six Nations bosses have confirmed rescheduled fixtures to complete the delayed 2020 tournament – and also plans for an eight-team expanded autumn Test series.
Ireland will host Italy in Dublin on October 24, before travelling to Paris to face France on October 31.
Wales are expected to take on Scotland at Twickenham, though there is still no official confirmation.
Cardiff's Principality Stadium remains a standby hospital in case of a second spike of the pandemic, with no date set before it can return as a rugby venue.
Six Nations chiefs revealed their delight in being able to complete this year's tournament, while also confirming the eight-team autumn series. Fiji and Japan are understood to be joining the Six Nations sides for the expanded autumn schedule.
The Women's Six Nations will be completed across the weekends of October 24, October 31 and December 5.
"We are absolutely thrilled to make this announcement today," said Six Nations chief executive Ben Morel.
"Whilst the past few months have been extremely challenging, we have always remained hopeful of concluding this year's tournament and we are really looking forward to the final games in the Men's and Women's Championships.
"There is still so much to play for, and we are hugely excited for what lies ahead.
"Public health remains the number one priority and while we must continue to be vigilant and cognisant of the dynamic and fast changing external environment, we are nonetheless extremely pleased to be moving in the right direction."
In confirming plans for the eight-team autumn Test tournament, Six Nations bosses conceded this would prove a one-off event due to the coronavirus impact.
"In recent weeks, Six Nations has also been progressing contingency plans for an alternative tournament format in place of the Autumn Internationals for 2020, primarily driven by travel restrictions not allowing many international teams to play the scheduled matches," read the statement.
"This tournament will be a unique eight-team competition, involving the Six Nations unions and two other international teams.
"We are currently finalising match schedules, operational details including venues as well as commercial arrangements.
"Further announcements relating to this competition are expected to be made later this month."
The Six Nations Under-20s tournament will not be completed however, with no team crowned champions for 2020.
Six Nations bosses are still working to determine whether supporters will be able to attend matches.
"In rescheduling these matches, the health and safety of players, associated staff and supporters has been at the forefront of our thinking," read a Six Nations statement.
"We remain in close contact with all relevant authorities across the respective jurisdictions to ensure these matches take place in a safe environment and we will announce further details of health and safety protocols and guidance on spectator attendance in due course.
"With regards to the U20 Six Nations championship, due to season scheduling constraints, it was decided that the three outstanding matches would not be played and there would be no winner for the 2020 Championship."
