The COSAFA Cup champions started their campaign with an emphatic 3-0 victory at home to Liberia in June last year before stealing a point away to Congo-Brazzaville - to remain top of the pool ahead of the DRC on goal difference.
A total of 13 players plying their trade in South Africa have been called up, with in-form Evans Rusike and Khama Billiat of Kaizer Chiefs and SuperSport United respectively - expected to play a leading role this month.
Both Cercle Brugge midfielder Nakamba and Amazulu's Karuru missed the 1-1 draw with Congo early in September due to injury.
The Warriors play the DRC in Kinshasa on October 10 before hosting the return leg in Harare three days later.
