He has brought in Bidvest Wits' Siyabonga Nhlapo, Kaizer Chiefs midfielder Reneilwe Letsholonyane, Sibusiso Khumalo of SuperSport United and Platinum Stars striker Siphelele Mthembu.
They come in for Oupa Manyisa, Teko Modise, Thabo Matlaba and Kermit Erasmus, who have been declared unavailable for various reasons.
Itumeleng Khune, Kagisho Dikgacoi, Tsepo Masilela, Siphiwe Tshabalala, Bernard Parker, Andile Jali, Siyanda Xulu and Sibusiso Vilakazi were also recently ruled out of contention, ostensibly for injuries and other unspecified reasons.
The upcoming friendlies against Australia and New Zealand fall outside of the Fifa calendar - meaning clubs are not obliged to release their players.
“I am very happy with this squad. As I said before, I have identified around 34 players who form the core of my vision and all these replacements are part of that bigger group. We are going to Australia and New Zealand to compete,” said Igesund.
Igesund and his men leave for Australia tomorrow and play the Socceroos on 26 May before facing New Zealand four days later. They return home on 1 June.
