The group of 43 players contains several new faces, plus the return of some familiar ones. Veteran halfback Tomás Cubelli is set to make his debut with the Jaguares after spending the 2018 Super Rugby season sidelined with a neck injury.
Joaquín Tuculet and Enrique Pieretto also make their return to the squad after recovering from knee injuries that kept them out in recent months.
The most notable absence is first five-eighth Nicolas Sanchez. The inspirational No. 10 linked up with Stade Francais for the 2018 Top 14 season in France.
The Pumas U20s also contribute a handful of graduates including Santiago Chocobares, Ignacio Mendy, Lucas Paulos, Santiago Carreras, Santiago Grondona, Lucio Sordoni and Mayco Vivas. The last four players were also selected for the Pumas in November.
The Jaguares will compete in their fourth season since they were introduced in 2016. They will be looking to improve on what was a watershed campaign in 2018, where they made the playoffs for the first time and finished the season with nine wins.
