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 24 October, before travelling to Paris to face France on 31 October - a day that will also see England take on the Italians in Rome, while Wales are expected to take take on Scotland in Twickenham.

The Women's Six Nations will be completed across three weekends, beginning on the weekend of 24 October, when Ireland play Italy, with the side concluding their campaign the following weekend. 

The Six Nations Under-20s tournament will not be completed however, with no team crowned champions for 2020. This is disappointing news for Noel McNamara's Irish side, who led the standings with three wins from three, prior to the lockdown.

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." 

News of the eight-team autumn series was also confirmed.

Fiji and Japan are understood to be joining the Six Nations sides for the expanded autumn schedule.

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 IRFU have also confirmed they will process refunds for the remaining Ireland matches.
