Boks release Ntubeni
Ntubeni, who did not travel with the team to Argentina on Wednesday this week, will be returning to Western Province.
He was one of the members of the broader Bok squad that stayed behind in Durban, while matchday squad headed to Buenos Aires for the final match ahead of the World Cup.
"Scarra [Ntubeni] has been working very hard in the last month or so and is familiar with how we play," Bok coach Heyneke Meyer said.
"After consultation with all relevant role players, we decided that it would be in his best interest to get some game time in the Currie Cup," the coach added.
* Meanwhile The Springboks were greeted by cold and wet weather when they arrived in Buenos Aires on Thursday – for the Test against Argentina.
Saturday's Test, at Vélez Sarsfield, will be the Boks' first encounter in the Argentine capital in almost a decade.
The last time the South Africans played there, was in November 2005.
South Africa have enjoyed good fortune in Buenos Aires before, but Springbok coach Heyneke Meyer is under no illusions about the enormity of the task that awaits his team.
"We were not good enough last week [a 25-37 loss in Durban] and the Pumas deserve full credit for their performance," said Meyer.
"Saturday's Test will be a massive challenge and we simply have to fire on all cylinders."
The Boks left Durban on Wednesday afternoon and travelled for approximately 24 hours to their hotel in Buenos Aires, which included a bumpy flight between Sao Paulo and Argentina.
They will have a light captain's run at the Test venue on Friday and will return to South Africa on Sunday.
