With the Rugby Championship well and truly wrapped up, a fight for places ahead of the 2019 Rugby World Cup intensifies when the Springboks host Argentina in a once-off Test match at Loftus Versfeld on Saturday afternoon.
Rassie Erasmus has made wholesale changes to his 20-man squad that sees Siya Kolisi make a return to the starting line-up since recovering from the serious knee injury he sustained in May.
The flanker missed out on the Rugby Championship and will slot in alongside Rynhardt Elstadt, with Marcell Coetzee, despite almost hanging up his boots last year, starting his first Test as an eighth-man.
South Africa will be led by 38-year-old veteran hooker Schalk Brits, who makes his first start since coming out of retirement in 2018.
The Pumas have also rang changes for this Rugby World Cup warm-up match, with as many as 10 players starting the match from the team that was dismantled by the Boks in Salta.
The clash starts at 16:00 from Loftus in Tshwane.
