Six Argentina players have been ruled out of facing Australia in the Rugby Championship on Saturday after making an unauthorised trip to Byron Bay.
Pablo Matera, Joaquin Diaz Bonilla, Felipe Ezcurra, Santiago Medrano, Santiago Socino and Sebastian Cancelliere were stopped at the state border when they attempted to return to their Gold Coast base from New South Wales on Wednesday.
Manager Lucas Chioccarelli and video analyst Rodrigo Martinez were also prevented from entering Queensland due to coronavirus rules.
The Argentine Rugby Union stated that the players will not be available to face the Wallabies in their final match of the tournament at Cbus Stadium this weekend.
Rugby Championship organiser SANZAAR said in a statement: "SANZAAR has informed Argentina Rugby that all members of this group are now ineligible to participate further in The Rugby Championship as they have breached tournament rules.
"SANZAAR is very disappointed that such a breach has occurred given the clear rules that are in place to ensure the health and safety of all players and staff, and compliance with all relevant health orders."
The Pumas are bottom of the table, having failed to pick up a point from five matches.
Meanwhile, Greg Holmes will become the oldest player to feature for opponents Australia since World War II at the age of 38 after the prop was named among the replacements by Dave Rennie.
Darcy Swain and Pete Samu come into the side, while back-rower Sean McMahon will also start on the bench as the Wallabies eye a fourth successive win to secure second place behind champions New Zealand.
