Argentina named Enrique Pieretto as a replacement for Santiago Medrano and Rodrigo Bruni for Pablo Matera in a reshuffled side for Saturday's Rugby Championship test against Australia after six players were ruled out for breaching COVID-19 rules.
Two staff members were also kicked out of the tournament earlier on Thursday for breaking rules by taking an unauthorised day trip to the New South Wales resort of Byron Bay, competition organisers said.
As a result, Medrano along with back row enforcer Matera plus team mates Sebastian Cancelliere, Joaquin Diaz Bonilla, Felipe Ezcurra and Santiago Socino were left out of the squad.
Australia thumped Argentina 27-8 in Townsville last weekend for their third straight test win. Argentina have lost all five of their matches so far.
A victory for the Wallabies will help them finish second behind New Zealand, who sealed the title with a victory over world champions South Africa in Townsville last weekend.
