Jaguares shuffle backs for Lions
The Jaguares' mentor has made six changes to the starting XV that suffered a 13-26 defeat against the Bulls.
However, the Jaguares will hope to end their South African tour on a high note against the Lions.
Perez has opted with the half-back pairing of Felipe Ezcurra and Nicolas Sanchez instead of last week's starters Gonzalo Betranou and Santiago Gonzalez Iglesias.
Scrumhalf Bertranou moves to the bench while flyhalf Gonzalez Iglesias is absent from the side.
Bautista Ezcurra steps in on the left wing and replaces Emiliano Boffelli, who takes up a spot on the bench.
At fullback, Ramiro Moyano gets promoted to the starting XV in the absence of Joaquin Tuculet.
On the side of the forwards, there are two changes. Flank Tomas Lezana gets the nod ahead of Pablo Matera. And Benjamin Macome will wear the No.8 jersey in place of Leonardo Senatore.
Jaguares: 15 Ramiro Moyano, 14 Santiago Cordero, 13 Matias Orlando, 12 Jeronimo De La Fuente, 11 Bautista Ezcurra, 10 Nicolas Sanchez, 9 Felipe Ezcurra, 8 Benjamin Macome, 7 Rodrigo Baez, 6 Tomas Lezana, 5 Marcos Kremer, 4 Guido Petti, 3 Ramiro Herrera, 2 Agustin Creevy (captain), 1 Lucas Noguera Paz.
