Heavy hitters Siya Kolisi and Eben Etzebeth return as Boks gear up for Los Pumas clash

Coach Rassie Erasmus also revealed that Sacha Feinberg-Mngomezulu, Lood de Jager and Morne van den Berg are part of the 26-man squad departing this weekend. The squad will travel to South America in two groups on Saturday.

Several players, who have been involved in the team's opening four matches of the season, such as Cheslin Kolbe, Damian Willemse, Jesse Kriel, and Ruan Nortje, among others, will reassemble at the team's training base in Johannesburg on Sunday to begin their preparations for the Rugby's Greatest Rivalry Tour against New Zealand.

"We tried to get the balance right between giving some guys who are returning from injury and who have not had too much game time in our last four matches a valuable run against Argentina, while at the same time managing the players who have played a lot of rugby this year," said Erasmus.

"The guys who have recovered from their injuries have been training hard this week and are ready to go, so it will be great for them to get a tough Test match under the belt before we face New Zealand.

"Several players, meanwhile, have been performing for us week in and week out, so it was important that we manage their workload, while players such as Ox [Nche] and Franco [Mostert] are still on the road to recovery, so next week's training camp will be useful for them to continue to put in the hard yards and for the injured players to continue their rehabilitation."

Erasmus added: "Argentina are a quality outfit and we know we will be in for a massive challenge in Buenos Aires, so we are preparing for a physical and gruelling battle over there.

"They are a well-coached team who have tested us in the last few years, while they have also been competitive in the Nations Championship, so it will be a good test for us as a team."

Commenting on the training camp this past week, which wrapped up on Thursday afternoon, Erasmus said: "We had a series of productive sessions throughout the week, and all the players know what we expect of them, so everyone understands the importance of building on our season."
