Brumbies halfback Tomas Cubelli has been named in Argentina's 28-man squad for next month's Tests against Italy and France.
The other 27 players picked in coach Daniel Hourcade's squad are part of the Argentine Jaguares franchise which made their Super Rugby debut this season.
Wing Emiliano Boffelli damaged knee ligaments during the Jaguares' 29-22 defeat by Kings in Port Elizabeth on Friday and will be out for the rest of the season.
Two players serving suspensions, prop Ramiro Herrera and lock Tomas Lavanini, will train with the squad until they become available.
The pair, sent off in Friday's match in Port Elizabeth, miss the June 11 Test against Italy in Santa Fe.
