Makhubedu, who is recognised as one of the best young coaches in the country, helped Sivutsa gain promotion to the First Division last season.
He has joined Jomo Sono as assistant coach; the first hint that Sono is loosening his vice-like grip of the coaching reins at Ezenkosi.

The Mpumalanga-born coach started his new job at Cosmos last week and is expected to sit on the bench with the club boss next season, as Ezenkosi look for another quick return to the Premiership.
Meanwhile, Cosmos midfielder Bamuza Sono tells KickOff.com that he will not be hanging up his boots just yet, despite being appointed club manager.
Sono says he will double up as a player and a member of Ezenkosi management committee next season.
"I am still 32 years old and I believe I still have a lot to offer playing football," Sono says.
