South Africa have made only one change to their starting XV for the Rugby Championship clash against Argentina at Twickenham.
Loosehead prop Ox Nche returns to the front row after missing the Durban test, taking the place of Boan Venter.
The Springboks will retain their Rugby Championship crown with a bonus-point victory regardless of the outcome between Australia and New Zealand in Perth.
If both South Africa and the All Blacks secure bonus-point wins, the title will be decided on points difference. The Boks currently hold a commanding +55 differential compared to New Zealand’s -6.
Sacha Feinberg-Mngomezulu remains at flyhalf after his record 37-point performance last week, which included a hat-trick of tries. Cobus Reinach continues at scrumhalf, with Damian de Allende and Canan Moodie in midfield.
Damian Willemse lines up at fullback alongside wingers Ethan Hooker and Cheslin Kolbe.
“This match is a Final for us, and we know how dangerous Argentina can be, so we selected combinations we feel will be best suited for this game,” said Erasmus.
“There are minimal personnel changes, with the bulk of the team having done the job for us last week against the Pumas in Durban and our other Castle Lager Rugby Championship matches.
“Ox and Grant could have played last week if we really needed them, but Boan (Venter) and Morne (van den Berg) did really well, while Jesse was rotated in the last two matches and is raring to go.
"The same applies to Bongi, who last played against Australia, and who is excited for this opportunity."
Argentina have already been eliminated from title contention, leaving pride as their main motivation. South Africa, meanwhile, enter as favourites, aiming to close the campaign with another dominant display to seal the trophy.
