Felix Jones has resigned as England's defence coach, continuing the recent upheaval in Steve Borthwick's backroom staff. Jones, who helped South Africa win back-to-back World Cups, introduced a promising blitz defence for England. His departure follows the exits of strength and conditioning head Aled Walters and fitness coach Tom Tombleson. Jones' resignation is reportedly influenced by Walters' move to Ireland, with whom he had a close working relationship. Despite Jones' 12-month notice period, his exit leaves Borthwick in urgent need of a replacement ahead of the upcoming season. The uncertainty also extends to Kevin Sinfield, whose future role in the team remains undecided.
