Andile Phehlukwayo has been added to the Proteas squad ahead of the second ODI against Australia in Bloemfontein on Saturday.
The all-rounder has been brought into the squad as cover for Sisanda Magala, who is recovering from an acute knee injury.
Meanwhile, Michael Neser has been added to the Australia squad.
Neser has been capped twice in ODIs and will join the team in Potchefstroom ahead of the third ODI.
“Ness is an experienced all-format cricketer who will provide us with an extra fast bowling option should that be required for the remainder of the tour,” said Australian selector Tony Dodemaide.
