The world's top rugby nations yesterday supported a review of the number of rest days between Rugby World Cup matches.
Cup minnows have been critical that they have had a shorter recovery time between matches than the top-tier countries at this year's tournament.
A meeting of the IRB's tier-one chairmen and chief executives in Auckland yesterday committed to playing mid-week matches during the 2015 cup to help achieve a better balance for tier-two and tier-three unions.
Delegates also unanimously recommended retaining the current format of 20 teams spilt across four pools.
The meeting also endorsed the commitment to review the cup commercial model, and revenue distribution.
