Argentina have made two changes to the starting team for the return Rugby Championship match against South Africa in Salta.
Centre Juan MartÃn HernÃ¡ndez, a late withdrawal from the side defeated 13-6 in Pretoria last weekend, returns at inside centre in place of Santiago GonzÃ¡lez Iglesias.
The other change is also in the backline with Lucas GonzÃ¡lez Amorosino coming in on the right wing for Horacio Agulla.
Worcester Warriors hooker Agustin Creevy skippers the Pumas and there are two ex-captains, Juan MartÃn FernÃ¡ndez Lobbe and Juan Manuel LeguizamÃ³n, in the back row.
Coach Daniel Hourcade has also made two alterations to the eight-man replacements list as Argentina seek a first Championship victory after a draw and 12 defeats.
Prop Bruno Postiglioni gets the nod ahead of Lucas Noguera Paz and Agulla takes the place of Amorosino.
