Round 3 of the Nations Championship sees England facing their third unique challenge in as many weeks as they journey to take on the formidable Pumas of Argentina.
This clash, set for the weekend of July 18, 2026, pits England against a Pumas side renowned for their ferocious scrum, relentless physicality, and passionate attacking play. Having navigated the Springboks' power and Fiji's flair, England must now contend with Argentina's all-encompassing threat, particularly in the breakdown and set-piece.
This fixture is a crucial test of adaptability and grit, with both nations desperate to secure points and position themselves strongly as the Summer Series concludes, making it an unmissable encounter.
