Francois Hougaard and Lwazi Mvovo have been recalled to the Springbok squad for their tour to Australasia.
Both players will come in for cover for injured Ruan Combrinck for the Rugby Championship clashes against Australia (Sept 10) and New Zealand (Sept 17).
Combrinck, who sustained a leg fracture over the weekend against Argentina in Salta, has been ruled out of action for up to six weeks.
Hougaard was not considered for the two Pumas Tests because of a knee injury, but the Springbok Sevens Olympian and Worcester Warriors player has since recovered and can play on the wing and scrumhalf.
Flyhalf Elton Jantjies will travel with the South African squad after he left the field early on Saturday with a deep bruise to the thigh.
Although cleared to tour, a call on his fitness for the Oz game will only be made later.
