South Africa director of rugby Rassie Erasmus has shuffled his front-row for the final round of the Rugby Championship against Argentina to be played in Salta on Saturday.
Tendai Mtawarira will make his 110th appearance for Springboks and will replace Steven Kitshoff at loosehead prop. Bongi Mbonambi returns as hooker with Malcolm Marx moved to the bench with Trevor Nyakane earning a promotion to take the tighthead prop position.
