Morne Morkel said South Africa will take not risk fellow paceman Dale Steyn if he is not fully fit for the third Test against India and feels the time has come for a match-winner to step up to the plate.
Steyn was ruled out of the drawn second Test in Bangalore after suffering a groin injury during the defeat in Mohali.
The world's number one Test bowler is also a doubt for the third Test in Nagpur - which starts on Wednesday - and Morkel explained that the tourists will not select him if there are any concerns that he could suffer a recurrence of his injury.
"We will give him until 9am on Wednesday to decide," said Morkel.
"It will be a medical call. You don't want to select a bowler if he is not 100 per cent fit, because the last thing you want is for him to break down and he can't bowl."
South Africa won at the VCA Stadium on their last visit for a Test five years ago and Morkel said they must show why they are the top ranked side in the world as they target a repeat of that success to level the four-match series.
He added: "It's important to take those memories and to put them aside. We need to play good disciplined cricket, we need to be tough regardless of what the conditions throw at us, we have to be in a mentally good place.
"We are the number one Test team in the world and we need to show that. Yes the conditions will be tough but somebody needs to put up their hand and take it on."
