Overview

• Head coach Felipe Contepomi reset the lineup with seven changes, starting Simón Benítez Cruz at scrum-half and Gerónimo Prisciantelli at fly-half, with Santiago Carreras shifting to fullback and Juan Cruz Mallía to the wing.
• Julián Montoya will captain the side for a 52nd test, setting the national record for most matches as Argentina’s skipper.
• South Africa enter on 15 points and play knowing the Australia–New Zealand result from Perth; the Springboks can clinch the Championship with a bonus‑point win.
