Argentina coach Mario Ledesma has sprung a surprise by naming Guido Petti to start at flanker for Test against Ireland in Dublin.

Ledesma has made five changes to the side that lost to the Wallabies 45-34 in the final round of the Rugby Championship.

Marcos Kremer drops out of the matchday 23 altogether and has been replaced by Matias Alemanno, as Petti shifts from lock to openside flanker.

Santiago Medrano takes the place of Ramiro Herrera at tighthead prop, while Santiago Garcia Botta comes in for Nahuel Tetaz Chaparro at loosehead.

Tomas Cubelli comes back into the scrum-half position for Gonzalo Bertranou, while Matias Moroni is replaced by Bautista Delguy on the wing.
