With a return fixture to come next week, Erasmus has rested a couple of key figures, with Siya Kolisi in the coaches’ box rather than on the pitch as he manages a facial injury. Argentina may therefore spy an opportunity to cause a shock — the hosts are full of confidence after producing a record win against Australia a fortnight ago.

South Africa can clinch the Rugby Championship with a game to spare this weekend. The world champion Springboks face Argentina in Santiago del Estero on Saturday.

Mateo Carreras, Pablo Matera and Joel Sclavi all forced their way over the line before a excellent dummy from Tomas Albornoz sent Argentina ahead. With Arendse restored just a few minutes before the break, Cobus Reinach sprinted in for a try and made it a four-point game heading into the second half.
