Palmerston North - Argentina have made five changes to their starting line-up which edged Scotland for Sunday's final Pool B match against Georgia.
Rodrigo Roncero and Juan Martin Fernandez Lobbe were both injured in the win over Scotland last weekend which put Argentina on track for the World Cup quarter-finals and have been replaced by Marcos Ayerza and Leonardo Senatore.
In a third change to the forward pack, lock Mariano Galarza replaces Manuel Carizza.
Lucas Gonzalez Amorosino, who scored the match winner against Scotland, was elevated from the bench to the starting line-up at fullback and Juan Jose Imhoff was selected on the left wing.
Gonzalo Camacho and Martin Rodriguez were left out.
Mario Ledesma Arocena was selected for his 17th World Cup match, just one short of Frenchman Raphael Ibanez' record for a hooker.
Pumas captain Felipe Contepomi needs to score 18 points to break Hugo Porta's Argentine record of 590 international points. Contepomi needs 26 to become Argentina's top scorer at a Rugby World Cup, a record currently held by Gonzalo Quesada who scored 135 points.
