A Cricket South Africa statement added: "The selection panel are placing an emphasis on the importance of game time for non-starting players and prefer that they are available to their teams to help boost the competition. They will join the national team if and when required."
Defeat by 189 runs to England in Cape Town means the series is squared at 1-1 heading into the matches at St George's Park and the Wanderers.
In 30 Tests played at the home of the Warriors, South Africa have prevailed on 14 occasions including in five of the last seven.
England meanwhile will be forced into at least one change from the second Test, with James Anderson ruled out the rest of the tour with a rib injury.
