The Anglo-Welsh Cup will be replaced next season by a 12-team competition involving just the Premiership sides, according to a report from the Guardian.
The new competition, known as the Premiership Rugby Cup, will give out a total of over £500,000 in prize money with financial incentives riding on every game.
England’s top-tier clubs will be split into three groups of four teams as the inclusion of Welsh regional sides ends after almost 13 years.
All four Welsh regions had featured in a 16-team Anglo-Welsh format since the 2005/6 campaign.
However, they have struggled over the past two seasons with squads stretched during international windows with all four finishing bottom of their pools in 2017/18.
This split comes with Pro Rugby Wales instead establishing an under-23 regional competition.
