This year's World Cup will be the first since World Rugby changed their eligibility rules in 2021.
That rule change has allowed test-capped players to represent a second nation that they are eligible for if they, their parents or their grandparents were born there, but only after a three-year stand down period from test rugby.
The move, while not restricted to Tier Two nations, will certainly benefit nations who have seen eligible players opt to play for bigger, more affluent countries. Specifically, the Pacific Islands have lost countless players over the years - with a similar rule change in rugby league resulting in Tonga reaching the semi-final and final in the last two World Cups.
