Cape Town - Argentina head coach Daniel Hourcade has made four changes to his starting XV for Saturday's Rugby Championship clash with Australia at Twickenham.
The big news is that veteran back-row Leonardo Senatore replaces first-choice number eight Facundo Isa, who hasn't recovered in time from a leg injury sustained in the Pumas 36-17 defeat against the All Blacks in Buenos Aires.
In the only other change to the pack, Lucas Noguera takes over from Nahuel Tetaz Chaparro at loosehead prop.
Meanwhile, in the back-line, Matías Moroni comes in for Santiago Cordero on the right wing and Manuel Montero replaces Ramiro Moyano in the number 11 jersey.
Montero and flyhalf Nicolás Sánchez will both face late fitness Tests before their participation in the Test is confirmed.
