Argentina coach Santiago Phelan finalised his replacements for Saturday's Rugby Championship clash against New Zealand.
Phelan revealed the Pumas' starting line-up on Tuesday, but had delayed naming his bench for this weekend's Test with the All Blacks.
The visitors are reinforced by the return of fly-half Juan Martin Hernandez and flanker Juan Manuel Leguizamon who missed the 16-16 draw with South Africa and bring the experience of 73 joint Test appearances to the starting XV.
Argentina will carry a degree of confidence with them from Mendoza where they had the better of South Africa for much of the game after opening with a 27-6 defeat to the Springboks in Cape Town.
Phelan said the Rugby Championship was a learning experience for Argentina which had previously lacked top flight international competition.
"This championship is not the World Cup but the level of toughness is bigger because at the World Cup you don't have each game against the best teams in the world and you don't have this travel," said Phelan.
"We want to grow up like a team. We want to improve our play with the ball, our attack system, our organisation in defence and keep developing players at this level - to play with the intensity that New Zealand and Australia, South Africa play at.
"Before this we'd play six games in a year, three in June, three in November," he added, saying the new championship "is very good for us."
