Beleaguered South Africa signalled the possibility of wholesale changes to their team for the last Test against England after recalling four players on Tuesday.
Batsmen Temba Bavuma and Keegan Petersen, left-arm seam bowler Beuran Hendricks, and all-rounder Andile Phehlukwayo will join the team in Johannesburg on Wednesday, and are expected to stand a good chance of playing when the last Test at The Wanderers begins on Friday.
South Africa have to do without top bowler Kagiso Rabada, suspended for the last test by the International Cricket Council, and are considering other changes, coach Mark Boucher admitted on Monday after the end of the fourth day in Port Elizabeth with his side on the brink of defeat.
There is growing speculation over the future of South Africa captain Faf du Plessis and that of several others batsmen after poor form in the series.
Squad: Faf du Plessis (captain), Temba Bavuma, Quinton de Kock, Dean Elgar, Zubayr Hamza, Beuran Hendricks, Keshav Maharaj, Pieter Malan, Anrich Nortje, Dane Paterson, Keegan Petersen, Andile Phehlukwayo, Vernon Philander, Dwaine Pretorius, Rassie van der Dussen.
