England's Rugby Football Union (RFU) has issued a stern warning to players considering joining a proposed breakaway global rugby league, stating that doing so would effectively end their Test careers. This warning comes as discussions intensify around a new league that aims to feature eight franchise teams and approximately 200 players, with plans to host matches in major cities worldwide. The initiative, reportedly backed by financial interests from the US and the Middle East, is set to launch in 2026. So far, around 20 players are believed to have expressed interest in joining the league. The RFU's position is clear: any player who signs up for the breakaway competition will not be eligible to represent England in international Test matches. This development poses a significant threat to the national team, which is already facing challenges under the leadership of coach Steve Borthwick. The potential loss of key players to the new league could have serious implications for the future of English rugby.
