Argentina have injected some vitality into their forward pack in making three changes to face the All Blacks in the Rugby Championship Test in Hamilton.

Pumas coach Daniel Hourcade has omitted two experienced forwards, flanker Juan Manuel Leguizamon and lock Tomas Lavanini, for Saturday’s Test from the starting team who upset South Africa 26-24 in Salta two weeks ago.

Seventy-Test veteran Leguizamon has been battling a quad muscle injury.

In their place come 21-year-old lock Guido Petti and 26-year-old openside flanker Javier Ortega Desio, who have both played less than 25 Tests. The pair impressed off the bench when the Pumas beat the Springboks on home soil for the first time.

A third change is forced on the visitors, with winger Matthias Moroni replacing the injured Manuel Montero. That switch prompted Hourcade to switch Santiago Cordero from the right wing to the left.

The reserves bench has also undergone a shuffle, with the most notable inclusion being uncapped 19-year-old flanker/lock Marcos Kremer.

Also on the bench is veteran loose forward Leonardo Senatore, who has served a 10-week ban for biting during a Super Rugby match for his Jaguares team against the Sharks.

Argentina:

Joaquin Tuculet, Matthias Moroni, Matias Orlando, Juan Martin Hernandez, Santiago Cordero, Nicolas Sanchez, Martin Landajo, Facundo Isa, Javier Ortega Desio, Pablo Matera, Matias Alemanno, Guido Petti, Ramiro Herrera, Agustin Creevy (capt), Nahuel Tetaz Chaparro. Reserves: Julian Montoya, Lucas Noguera, Enrique Pieretto, Marcos Kremer, Leonardo Senatore, Tomas Cubelli, Santiago Gonzalez Iglesias, Ramiro Moyano.
