South Africa's premier batsman Jacques Kallis will play in the Standard Bank Pro20 match against New Zealand at the Wanderers.
Kallis was left out of the South African team for the World Twenty20 tournament earlier this year.
His disappointment at his omission led him to resign the vice-captaincy of the Proteas team, and he also threatened to reconsider his future in South African cricket.
Proteas captain Graeme Smith had a steely look in eye when asked about Kallis.
"Jacques Kallis will play tomorrow [Friday]," he said.
Smith said Shaun Pollock, who sat out the two Tests against New Zealand, would also play in the Pro20 match.
Smith said the team was looking forward to the limited overs series against New Zealand, but would not underestimate their capabilities.
"New Zealand as a one-day team and a Twenty20 team are very respectable," he said.
"They've churned out some really top performances in the past, so we do know what they're capable of. We've got to get back down to earth now, and put in the work.
"We've played enough against New Zealand to know that they're a very competent team. They will have licked their wounds after the Test series and they'll want to come back at us. They're a lot better one-day team than they are a Test team, and they've always played well against us. I expect them to be very competitive in this series."
He said he was very pleased with the consistency shown by the selectors, who made just one change to the one-day squad, bringing in fast bowler Dale Steyn for Justin Kemp.
"The selectors are giving us a chance to work with players and build an environment that is capable and that breeds success. The more we spend together, the better the results have got."
He said Steyn still had a lot of work to do to cement his place in the one-day team.
"His confidence is very high at the moment. He will more than likely get a run-in tomorrow night in the Twenty20, and hopefully he will be as explosive as he was in the Test series.
"He's never going to be a defensive bowler. Someone who bowls at that pace, you're never going to use him in a defensive way. You can't have a strike bowler who's going at 15 an over.
"You've got to be clever with the field settings and the way you use him. As he's matured in the Tests, he's going to have to mature in the one-day format too. If he can strike for us, he's going to go a long way to claiming his spot."
Smith said the fact that New Zealand reached the semifinals of the World Twenty20 while South Africa were knocked out in the group stages did not give the Black Caps a psychological advantage.
"We beat them in the Twenty20," he said.
"We only lost one match in the tournament, whereas there were teams that were in the semifinals that lost two. So that definitely doesn't give them the edge."
