Argentina have made two changes to the starting team for the return Rugby Championship match against South Africa in Salta.
Centre Juan Martín Hernández, a late withdrawal from the side defeated 13-6 in Pretoria last weekend, returns at inside centre in place of Santiago González Iglesias.
The other change is also in the backline with Lucas González 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 Martín Fernández Lobbe and Juan Manuel Leguizamón, 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.
