Chile and Argentina kick off Nations Cup with high‑stakes matches

Chile opens the Nations Cup against Romania at Santiago’s Estadio Nacional. The lineup is dominated by Selknam players, with Martin Sigren starting at flanker and Santiago Videla on the bench. Chile’s 40‑16 victory over Romania last year raises hopes of a ranking boost, while Romania returns injured backs Gabriel Rupanu and Marius Simionescu and debuts JP Smith.

Argentina’s Pumas begin their Nations Championship campaign versus Scotland in Córdoba. Coach Felipe Contepomi fields a refreshed squad after a rebuilding period, resting several Top 14 finalists and introducing newcomers such as Agustín Fraga and Juan Penoucos. The side aims to improve match‑by‑match ahead of the 2027 Rugby World Cup, with the opening match seen as a test of their new structure and depth.
