Argentina have named a 30-man squad for their training camp in Florida over the next two weeks before The Rugby Championship.
The squad will depart on Wednesday for their base in the United States, where they have trained for the last three years, returning to Argentina on July 10.
Juan Martín Fernández Lobbe is set to lead the Pumas once again, while three of the backs - Nicolás Sánchez, Joaquín Tuculet and Lucas González Amorosino - are unattached.
Maximiliano Bustos has not been included in the squad as he continues recovering from a hernia operation.
After returning from Florida, Argentina's match preparations will commence on July 14 before playing two friendlies against Top 14 side Grenoble on July 26 and August 2.
