Siya Kolisi will make his first Test appearance of the season when he captains the world champions against Argentina in Buenos Aires on Saturday. His return is one of 13 changes to the line-up that started a 43-0 romp against Wales in Durban last month. Apart from Kolisi, the Argentina Test presents a number of other South Africans a first Test outing of the season after missing the three home internationals during June due to injury. Scrum-half Morne van den Berg, another recent injury casualty, is one of two backs in a six-two split on the bench. "The guys have been working very hard to return from injury, and there is no better test to measure where they are than facing the Pumas in Argentina."
