Argentinian coach Santiago Phelan has made three changes to his squad for Saturday's international with Ireland in Dublin.
Horacio Agulla is out after suffering concussion in Saturday's 39-22 defeat to France, whilst Lucas Gonzalez Amorosino and Juan Figallo are dropped.
Fit-again Juan Martin Hernandez returns along with Santiago Fernandez and Maximiliano Bustos.
Wing Agulla had to be stretchered off after being involved in a horrible clash of heads with Maxime Mermoz.
Hernandez returns after recovering from a knock he took in the 26-12 win over Wales the previous week.
Fernandez and Bustos, who both play their club rugby in France for Montpellier, are added to the squad.
