Joaquín Tuculet will start at fullback for the Jaguares against the Sharks in Buenos Aires on Saturday.
Tuculet and outside centre Matias Orlando return to the starting lineup as Matias Moroni and Santiago Cordero are unavailable due to commitments to the Argentina Sevens side. In a positional change, Emiliano Boffelli moves to the right wing.
The only change to the pack sees Pablo Matera replace Tomás Lezana at openside flank.
