Pumas change three for decider
In the forwards Tomás Lavanini returns from the suspension - for foul play - slapped on him during the final round of Super Rugby action before the June Test season.
As a result Javier Ortega Desio moves to the back row and Thomas Lezana drops down to the replacement bench.
Among the backs Thomas Cubelli will start in place of Martin Landajo at scrumhalf and Jeronimo de la Fuente replaces Juan Martin Hernández at inside centre - after Hernández was injured in last Sunday's Test.
Matías Orlando and Lucas González Amorosino return to the matchday squad and will both play off the bench - with the latter set to earn his 50th cap if he takes to the field.
