After 16 League games SuperSport are eighth on the log with 20 points, but they have only scored 19 goals.
In a chat with KickOff.com, SuperSport coach Gavin Hunt says he is happy to have Sithole.
"His papers are almost sorted out and he should be available for selection against Orlando Pirates on Wednesday.
"He is a useful striker with an eye for goal and hopefully he will make a big difference for us up-front," Hunt tells KickOff.com.
The 22-year-old Sithole was previously on the books of Shooting Stars, CAPS United, Sundowns and Dynamos.
