The Pumas will be without their first-choice halfback pairing of Tomas Cubelli and Nicolas Sanchez for the rest of the test series. Cubelli tore a thigh muscle in the warm-up before Saturday's 26-18 win in the first test in San Salvador de Jujuy while Sanchez suffered a calf tear early in the game. Scrum-half Felipe Ezcurra will also join the squad.
Two other Warriors - Enrique Pieretto and Sebastian Cancelliere - are in a shadow Argentina squad that will face Georgia and Portugal in Europe.
