Los Pumas head coach Mario Ledesma has named an unchanged run-on side to the one that was well beaten by New Zealand last week, with Santiago Carreras retained at flyhalf with first-choice No.10 Nicolas Sanchez still out injured.
There are a few changes on the bench.
Rodrigo Martinez takes over the No.17 jersey from Carlos Muzzio, while Joaquin Oviedo also gets a place on the bench with Tomas Lezana dropping out of the matchday squad.
The other change to the bench sees Mateo Carreras come in for Matias Moroni.
