Zane Kirchner and Dewald Potgieter will train with the Springboks for the rest of the week.
Coach Peter de Villiers didn’t say whether the pair will be considered for selection for the third Test.
‘Zane and Dewald impressed against the Lions and we felt there was an opportunity to invite them to training this week with a view to their possible future involvement in the Springbok squad,’ said De Villiers.
The pair both featured in the Emerging Boks’ 13-all draw with the Lions last Tuesday, while Kirchner was a surprise omission when the original squad was named without a specialist fullback.
The Boks completed their first practice of the week on Tuesday morning, while the team for the final Test will be named on Thursday as De Villiers waits on the availability of certain individuals.
