The influential back-rower picked up an ankle injury in the 13-12 victory over Scotland but he has been given the green light to play.
The Pumas will be without Juan Martin Fernandez Lobbe and Rodrigo Roncero, though, so Leonardo Senatore and Marcos Ayerza come into the starting XV.
Lock Mariano Galarza, full-back Lucas Amorosino, who scored the winning try against Scotland, and winger Juan Jose Imhoff are also handed starts in Palmerston North.
Georgia have dropped fly-half Merab Kvirikashvili to the bench for the final Pool B encounter.
Kvirikashvili, who started all three of Georgia's games in New Zealand, has been replaced in the No.10 shirt by Lasha Khmaladze.
Khmaladze switches from full-back, with Malkhaz Urjukashvili coming into the side, while Viktor Kolelishvili comes in for Dimitri Basilaia, with Mamuka Gorgodze starting at No.8.
