With 13 changes from the Wales game and a squad riddled with players returning from injury, Erasmus is going into Saturday's clash in Buenos Aires with managed expectations — but Kolisi's fitness isn't one of his concerns. Despite missing all test rugby in 2026 until now, Erasmus says Kolisi has a track record of diligent, on-schedule rehab that means he's never a selection risk after a layoff. The skipper is expected to play just over a half before making way for Van Staden. The bigger unknowns are Etzebeth and De Jager, both of whom have had minimal game time at any level this year. Their bench replacements — Dixon and Wiese respectively — have been selected with lineout-calling continuity in mind, with Wiese taking over De Jager's calling duties and Dixon slotting straight in for Etzebeth. Feinberg-Mngomezulu hasn't played since the URC quarterfinals, Moodie and Hooker are also working back to full fitness, and Pollard is carrying his own injury disruptions. Erasmus is explicitly not targeting a winning margin — just a win, some cohesion, and signs of a growing game plan against a Pumas side he expects to make it a physical grind.
