Springbok flanker Willem Alberts could miss Saturday's clash against Wales in Cardiff due to injury.
The 32-year-old left the field in South Africa's defeat to Italy in Florence, after receiving a blow to his neck, and the Boks' forwards coach Matthew Proudfoot said there would be more clarity on the player's availability for this weekend's Test by Monday.
Oupa Mohoje is the logical replacement if Alberts is unable to play, although Jean-Luc du Preez and Uzair Cassiem are also in the running to make their Test debuts.
“Jean-Luc is someone we are considering for that position, Uzair fared well for the Cheetahs and Oupa has played there before," Proudfoot told Netwerk24.
There could also be other changes in the Boks' loose trio. If it's about continuity, then Warren Whiteley will be retained at number eight and Nizaam Carr on the other flank.
But the lack of physicality was evident in Florence and that is where Du Preez or Cassiem will be useful. Proudfoot admitted that they lacked a physical dimension in Florence but said that the entire pack came off second best in that facet of play.
“That wasn't the case among the loose forwards alone,” he added.
“We couldn't scrum as well as we did against the English. The lack of physicality at the driving mauls was 'n problem. We carried the ball well but didn't do well in contact."
