Sachin Tendulkar is most likely to bat lower down to lend solidity to the middle-order in the absence of injured Rahul Dravid, team sources said ahead of the start of the fourth one-dayer in Port Elizabeth on Wednesday.
Mumbai batsman Wasim Jaffer would replace Dravid in the squad which might also see Irfan Pathan give way to pacer S Sreesanth for the day-night encounter against the hosts.
New ball bowler Munaf Patel does not seem to have recovered from the sore left ankle that kept him out of India's previous game against South Africa in Cape Town on Sunday as he was not included in the list of 12 for this tie.
Suresh Raina and Dinesh Mongia continue to be out of reckoning after being ignored for the third game which India lost by a whopping margin to trail South Africa 2-0 in the series. The first game in Johannesburg was washed out.
