Cricket South Africa has approved a request from the Dolphins for Kevin Pietersen to play two games for his former team next month.
The South African-born England batsman will play for the Durban-based Dolphins in two four-day games in the domestic SuperSport Series in a bid to regain his form ahead of the Ashes series in Australia.
He will play against the Warriors from October 7-10 and against the Titans from October 14-17.
Pietersen made his first-class debut for the Dolphins, then known as Natal, in 1997 before pursuing a career in England. He qualified to play for England in 2004.
Pietersen was dropped from England's Twenty20 and one-day teams last week and hasn't scored an international century in 18 months.
