Sikhakhane was a former Premier Soccer League coach and most recently was in charge of NFD side Royal Eagles.
He was assisted by former Crystal Palace midfielder Kagisho Dikgacoi, as well as Sazi Ngubani who were both filling in when the head coach couldn't continue.
He had previously promoted Thanda Royal Zulu into the PSL, and was trying to do the same with Royal Eagles.
The South African made a name for himself as Vladislav Heric's assistant when they won the NFD back in the 2013-14 season.
