Well going back to SA and changes they can make, well a replacement for Dale is a must, it could be Nel or Zondeki, I believe the one that perform in this current match will get the nod, but also, Harris have not impressed, one can say the quicks did the work in the 2nd test so he got a let off, but there is Robin Peterson, bowls say style as Harris, and his test figures are almost identical, so he could be given a nod as well, and it appears that Harris himself might have an injury, not serious, but one none the less, there is the belief that a team that won a test match should not be changed, and I agree, but I also believe that a player with an injury, no matter how small, should not be carried into a test match.
I guess we just have to wait and see.
