Argentina Head Coach Daniel Hourcade has made one change to his starting line-up to face Wales in the second Test at Estadio Brigadier Estanislao López.
Veteran scrum-half Martin Landajo comes in for Gonzalo Bertranou in the only change to the Pumas side as they look to bounce back from defeat in San Juan and level up the series.
