Overview

• Coach Felipe Contepomi makes seven changes, with Simón Benítez Cruz replacing injured scrumhalf Gonzalo García and Gerónimo Prisciantelli starting at fly-half as Santiago Carreras shifts to fullback.
• Julián Montoya captains for the 52nd time, becoming Argentina’s most-capped captain.
• South Africa lead the table on 15 points and can secure the title with a win, with bonus-point scenarios in play depending on Australia vs. New Zealand.
• Australia host New Zealand in Perth earlier on Saturday, meaning the Springboks will know what they need before kickoff at Twickenham.
• The match starts at 10:00 in Argentina and airs on ESPN and Disney+, while the competition is not scheduled for 2026 due to NZ–SA tours and its post-2026 format remains under discussion.
