South Africa lock Franco Mostert has been recalled in the only change to the starting line-up for the Rugby Championship return match against Argentina in Mendoza tomorrow. The forward, a recent signing by English Premiership outfit Gloucester from the Johannesburg-based Golden Lions, replaces Pieter-Steph du Toit, who drops to the bench. 
In changes among the substitutes, tighthead prop Wilco Louw and lock RG Snyman come in and Thomas du Toit, Marvin Orie and Marco van Staden are omitted.  
South Africa came from nine points behind during the first half in Durban last Saturday to score a bonus-point 34-21 victory. They share first place with New Zealand. Erasmus resisted the temptation to reshuffle his back row of flankers Francois Louw and captain Siya Kolisi and number eight Warren Whiteley, who were average last weekend.
