Jaguares winger Manuel Montero has been ruled out of Saturday's clash with the Hurricanes due to injury.
Montero was scheduled to start in the back three for the Argentine franchise but suffered a hip strain during training on Thursday.
As a result Ramiro Moyano comes off the bench to take his place on the wing, with Joaquín Paz now named amongst the replacements.
Montero, 24, missed last year's Rugby World Cup with Argentina through injury after rupturing his ACL.
