Argentina have made one change for Sunday's World Cup semi-final with Australia, Marcelo Bosch returning in place of Matias Moroni at centre.
Saracens centre Bosch missed the quarter-final win over Ireland after serving a one-week ban for a dangerous tackle against Namibia on 11 October.
Captain Agustin Creevy has passed a fitness test following a leg injury.
The Pumas, competing in their second semi-final in three World Cups, are seeking to reach a first final.

Moroni scored Argentina's first try against Ireland but head coach Daniel Hourcade has included the experienced Bosch for his defensive skills.
Martin Landajo has again been given the nod over Tomas Cubelli in the fight to start at scrum-half.
There is also one change to the bench with the addition of prop Juan Figallo, who came into the tournament as a late replacement for the injured Nahuel Tetaz Chaparro near the end of the pool stage.
Figallo, who when fit was an automatic first choice for the Pumas in the Rugby Championship, missed out on the original World Cup squad after surgery on damaged knee ligaments.
Juan Pablo Orlandi, the prop called up in his place for the tournament, makes way.
