Cape Town - Siya Kolisi will continue to lead the Springboks in the upcoming Rugby Championship, the KEO.co.za website reports.
Springbok coach Rassie Erasmus will name a 32-man squad at 11:00 on Monday.
No 8 Warren Whiteley will return to the squad, but he will not take over the captaincy from Kolisi, who was initially only appointed as captain for the three-Test series against England.
Whiteley will replace Duane Vermeulen, who will miss the Rugby Championship due to club duties in Japan.
Whiteley captained the Springboks at the start of the 2017 season but injuries cut short his season and the curse struck again this year which saw him miss the England series in June.
However, it appears Kolisi has done enough to keep the captain’s armband after leading the Boks to a 2-1 series win over England.
The Boks open their Rugby Championship campaign against Argentina in Durban on August 18.
