Argentina captain Agustín Creevy will win his 50th cap for his country when he captains the side against South Africa this weekend.
Veteran flanker Juan Manuel Leguizamon is joined in the back row by Pablo Matera and Facundo Isa, while Martín Landajo and Nicolás Sánchez make up the half-backs.
Nahuel Tetaz Chaparro and Ramiro Herrera will pack down in the front row alongside Creevy, supported by a second row of Matías Alemanno and Tomas Lavanini.
In the back-line Juan Martín Hernández is named at inside centre, with Matías Orlando outside him, while Manuel Montero, Santiago Cordero and Joaquín Tuculet all make up the back three.
