Juan Martin Hernandez will likely start the first match
Argentina will be without the injured Patricio Albacete and suspended Leonardo Senatore for Rugby Championship matches in Australia and New Zealand.
Lock Albacete, who had already missed the Pumas' second match of the tournament against South Africa last weekend, which the Springboks won 22-17, is suffering from a torn hamstring.
Senatore will miss out on the two matches, against New Zealand on September 7 and Australia a week later, after picking up a nine-week ban for biting.
Fullback Juan Martin Hernandez will likely start the first match after missing out with injury last week, while Toulon flank Juan Martin Fernandez Lobbe also makes the trip.
