Usuthu recently recruited Khenyeza on a one-year deal from Golden Arrows.
The 34-year-old, who has scored over 100 goals in the PSL, will partner Siyabonga Nomvethe upfront at the NFD outfit.
“Mabhuti will be a massive acquisition for the club because we know what he’s made of,” Antipas told the club's website.
"He is a big personality and I’m certain he will help the youngsters and others playing around him and 'Bhele' Nomvethe.”
Antipas is also pleased with the acquisition of Tumelo Letuka (two-year contract) and fellow defender Njabulo Ngcobo (three-year deal) from Durban Warriors and Arrows respectively.
“Njabulo is an upcoming player with a good attitude. What I like about him is his aggressiveness, he’s a no-nonsense defender,” said Antipas.
He added: “Tumelo is an experienced left-footer who will contribute a lot and also help the younger players around him."
