Argentina have made four changes to their squad for their next two games in the Rugby Championship in New Zealand and Australia.
Leicester Tigers' prop Gaston Cortes is one of four new faces brought in to help them maintain momentum after their win over South Africa at the weekend.
Cortes is joined by loose forward Juan Manuel Leguizamon, who last played for the national side in last year's 28-19 defeat by Ireland.
Julian Montoya, the hooker who missed the two-match series against South Africa through injury, is back, as is centre Matias Orlando.
The four go into a squad on a high after beating South Africa 32-19 in Mendoza on Sunday to record just their third win in the Rugby Championship since they joined the tournament in 2012.
The Pumas' win ended an 11-game losing streak in the tournament and sets them up nicely for tough fixtures against New Zealand in Nelson next week and Australia on the Gold Coast a week later.
The All Blacks top the table with two wins out of two against their closest rivals.
The All Blacks will play there first test in Nelson when they host Argentina there on September 8th.
