Veteran Matias Moroni was one of three changes made to the Argentina team announced on Wednesday by head coach Michael Cheika to play Samoa in the World Cup this weekend.
The 32-year-old, who is the only Pumas player to play in all six of their tests this year, comes in at outside centre in place of Lucio Cinti, who drops to the bench compared to the team that lost 27-10 to 14-man England in their opener.
Eduardo Bello replaces Francisco Gomez Kodela at tighthead prop and Guido Petti comes into the second row as Tomas Lavanini misses out on the matchday 23 for Friday's Pool D clash in Saint Etienne.
Gomez Kodela is on the bench where prop Mayco Vivas was preferred to Joel Scalvi.
Veteran flyhalf Nicolas Sanchez and scrum-half Tomas Cubelli are on the bench but half-back Lautaro Bazan Velez misses out.
