Argentina head coach Mario Ledesma has also rung the changes to his starting XV for their Rugby Championship Test against the All Blacks in Brisbane.
There are six alterations in all, including two positional switches, with Pablo Matera moving to number eight from the blindside flank, where he takes over from Rodrigo Bruni, while Santiago Cordero shifts from the left to the right-wing in place of Bautista Delguy.
Matera’s spot on the side of the scrum is taken by Juan Martín González while Emiliano Boffelli will wear the number 11 jersey.
In other backline changes, Santiago Carreras replaces Nicolas Sanchez at fly-half while Santiago Chocobares and Lucio Cinti are preferred to Jeronimo De La Fuente and Matias Moroni as the new centre combination.
There is one final change in the forwards with Tomas Lavanini coming into the run-on side in place of Guido Petti, who has been demoted to the replacements bench.
