Nations Championship 2026: Latest team news and November fixtures

The 2026 Nations Championship returns this week as the Northern Hemisphere teams prepare for a demanding series of international fixtures against some of the world's strongest rugby nations.

The fourth round begins on Friday, November 6, when Ireland host Argentina in Dublin. Saturday's programme includes Scotland against New Zealand and Wales against Japan, while England face Australia at Allianz Stadium on Sunday.

Several team-selection stories have already emerged ahead of the opening fixtures. Ireland will be without centre Garry Ringrose, who is expected to miss the upcoming matches against Argentina, Fiji and South Africa while recovering from a hamstring injury. Head coach Andy Farrell has also handed scrum-half Craig Casey a starting opportunity against Argentina.

England, meanwhile, have named a 36-player squad for their autumn campaign, although Alex Mitchell has been ruled out after suffering a hamstring injury. Fin Smith has been included despite missing the team's recent training camp.

Wales have selected Sam Costelow at fly-half for their meeting with Japan, with Tomos Williams partnering him at scrum-half. Head coach Steve Tandy has also made changes to his midfield, while captain Dewi Lake will lead the side in Cardiff.

The November series will play a major role in determining the final Northern and Southern Hemisphere standings ahead of Finals Weekend, which takes place from November 27 to 29.
