## Pool C
### Argentina

On 16 August, Argentina announced their initial 31-man squad.
Hours after the 31-man squad was announced, Matías Díaz suffered an injury and was replaced in the squad by Juan Pablo Orlandi.
$^1$ On 15 October, Juan Figallo was called up to the squad to replace Nahuel Tetaz Chaparro after he suffered an injury in training.
$^2$ Due to an injury to Agustín Creevy, usual prop Lucas Noguera Paz will cover hooker from the bench against South Africa in the Bronze Final. However, an injury sustained in training for prop Marcos Ayerza ruled him out of the Bronze Final the day before the match, and Santiago García Botta was called up as his replacement. As there was no further cover for prop, García Botta was cleared to play in the match, despite the stand-down period of 48 hours before an injury replacement can take the field, though he is only permitted to play if absolutely required.
