But sources in the PCB told PTI that the national selectors were told by the Board that Misbah will continue as captain for both formats while Mohammad Hafeez has been retained as captain of the T20 squad.
Pakistan leaves on January 20 for South Africa to play three Tests, five one-dayers and two T20 matches.
"Board chairman Zaka Ashraf is happy with the performance of Misbah and the way he led the team to the one-day series win in India recently," one source said.
"The positive report about Misbah is that despite his age, he is fit and brings about lot of confidence and discipline to the team with his presence and leadership qualities," the source said.
He said the Board had decided to continue with Misbah for the South African tour while Hafeez would be groomed to take over from him after the Champions Trophy in England this year.
Misbah has said after returning from India that he had no intentions to quit ODI cricket as he enjoys the format and is fit for it.
"There is a concept in Pakistan that someone of my age shouldn't be playing cricket at the top level. I disagree, I made my debut late and I believe as long as someone is fit and ready to perform at the highest level there is nothing wrong with him carrying on," Misbah said.
The national selectors have been told to finalise squads for the South African tour and submit them to the Board.
Sources close to the selectors said Asad Shafiq, after recovering from a injury, was certain to replace Umar Akmal in the middle order while Taufiq Umar would return as the opener for the Tests.
