England, Wales and Ireland are set to face Georgia instead of Fiji in the autumn’s new eight-team tournament.
Fiji were originally drawn in that pool but changes are expected following Japan’s withdrawal because of coronavirus travel restrictions and Georgia’s likely inclusion.
Fiji are now set to replace Japan in a group alongside Scotland, France and Italy.
The tournament is due to start on 14 November with a 5 December final.
Full details are yet to be confirmed but the competition is serving as a replacement for the scheduled autumn Test series after Covid-19 restrictions initially prevented southern hemisphere sides from travelling to Europe.
South Africa were also linked with joining the tournament after Japan’s withdrawal, World Rugby vice-chairman Bernard Laporte saying there were “advanced discussions” with the world champions.
