Hashim Amla and Robin Peterson have been withdrawn from the Proteas' squad for the final one-day international against New Zealand in Potchefstroom tomorrow.
Dean Elgar has been added to the squad.
Amla sustained a strain to his right quad muscle on Monday afternoon, while Peterson received stitches for a split webbing to his right hand during the second ODI defeat on Tuesday.
Aaron Phangiso will be included in the team in place of Peterson.
Tomorrow's match is a dead rubber as the Black Caps have already won the series 2-0.
