South African middle-order batsman Temba Bavuma, who was part of the squad but did not make the eleven in the first two Tests, will not be available for the third Test here because of a fractured right finger.
Bavuma suffered the injury during a domestic match and will be out for at least a month.
South Africa already has injury worries with opener Aiden Markram facing a fitness test, ahead of the Test beginning here on Wednesday, for a quad strain.
Theunis de Bruyn is the extra batsman in the squad and can open the innings.
