Seb Atkinson Handed First Six Nations Start as Borthwick Overhauls England Backline

London, 3 March 2026 – England head coach Steve Borthwick has made a significant tactical shift ahead of the Round 4 Six Nations clash against Italy, naming Gloucester centre Seb Atkinson in the starting XV. The 23-year-old is set to earn his first start of the tournament as part of a major reshuffle following England’s recent defeats to Scotland and Ireland. Atkinson replaces Fraser Dingwall in the number 12 jersey, partnering Tommy Freeman in a revamped midfield designed to provide both physical presence and distribution skills.

The “Bronco Beast” Steps Up

Atkinson’s inclusion comes on the back of a standout season for Gloucester, where he has earned a reputation as one of the most conditioned players in the Premiership. Known as the “Bronco Beast” of Kingsholm, Atkinson holds a world-record time for the “Bronco” fitness test, a grueling aerobic shuttle run used to measure endurance in rugby union. His transition to the international stage follows a resilient career path, having successfully navigated the collapse of his former club, Worcester Warriors, in 2022 before finding a new home and “freedom” under the coaching staff at Gloucester.

Borthwick’s decision to “roll the dice” includes nine personnel changes in total. Atkinson will line up alongside fly-half Fin Smith, who also earns a start, as England looks to inject creativity and “grunt” into a backline that has struggled for consistency in the opening rounds of the 2026 championship.
