Jaguares head coach Raul Pérez has opted to make three changes to his side for their clash with the Sharks in Buenos Aires.
Coming off their bye week the Jaguares make two changes to their backline, with Joaquín Tuculet returning at full-back and Matías Orlando starting at outside centre.
Matías Moroni and Santiago Cordero both make way due to their involvement with the Argentina Sevens side in Paris.
The final change sees Pablo Matera take over from Tomás Lezana in the back row.
