Felipe Contepomi has been named in Argentina's squad to face England and Georgia in June.
The flyhalf ended his European club career at Stade Francais but expressed a wish to play again for Argentina this year.
"It's a very demanding window which is a nice opportunity to see a lot of players in action," said Argentina manager Santiago Phelan.
"They will be very intense matches and top notch.
"Although England won't have their players touring with the British and Irish Lions, they will be a top level team and their players compete in very demanding leagues."
The Pumas will face England on June 8 in Salta, and meet Georgia a week later.
