Jaguares head coach Raúl Pérez has made two changes to his starting team that will face the Lions at Vélez Sarsfield on Saturday.
Due to an injury to captain and hooker Agustín Creevy, Julian Montoya comes into the side for their final fixture of their Super Rugby season.
The other alteration to the side that lost to the Highlanders last weekend sees Pablo Matera miss out so Javier Ortega Desio moves to the flank and Guido Petti comes into the second-row as they look to finish on a high note.
