Zuko Gxabuza got the call-up from Sono after impressing in the National First Division outfit's youth structures.
“Yes, we have signed the boy from our development, and we are hoping to make him an even better player in the shortest time possible,” Sono told his club's official website.
Sono, whose charges came up short in the promotional play-offs in 2017/18, has developed a number of stars over the years, including Bafana Bafana legends Mark Fish, Sizwe Motaung, Phil Masinga and Helman Mkhalele.
