The Springboks come into this match sitting top of the Rugby Championship table on 18 points, following back-to-back home wins against New Zealand. Meanwhile, Argentina are in third place on 10 points, having kept their hopes of a first-ever southern hemisphere title alive with a record-breaking victory over Australia last weekend.
It is a hot and humid day in the capital city of Argentina's northern province. The Springboks have been welcomed by temperatures hitting the upper 30 degrees for their first-ever match in Santiago del Estero and will be around 37 degrees by kick-off.
