Argentina have added a handful of senior players to their squad for Saturday's rematch with South Africa in Buenos Aires.
Having beaten the Springboks for the first time in history last weekend, los Pumas have reinforced their squad with the return on former skipper Martín Fernández Lobbe, first-choice fly-half Nicolás Sánchez as well as wing Santiago Cordero, loose forwards Javier Ortega Desio and Facundo Isa and centre Matías Moroni.
They join the players that travelled to Durban last week with the exclusion of centre Jerónimo De la Fuente, who has been ruled out due to a rib injury.
Argentina have carefully managed the game time of their players during the Rugby Championship but are set to name their first-choice XV for the first time this year.
Head coach Daniel Hourcade is set to name his starting XV on Wednesday and will announce his final World Cup squad on Sunday.
The Test at Vélez Sarsfield will be the last for Argentina and South Africa before the September 18 kick-off of the RWC in England. Argentina are in Pool C with title-holders New Zealand, Georgia, Namibia and Tonga.
