Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
If boxing matches were purely verbal contests then the career of Osborne "Big Daddy" Machimana would come to a screeching end against Zack "Black Warrior" Mwekasa.
Loudmouth Mwekasa has threatened to eat Machimana alive.
Machimana, the local heavyweight champion who is trained by Nick Durandt, should silence the motor mouth.
Mwekasa wants to fight Machimana in a 10-rounder because he cannot fight for the South African title as he is a foreigner.
The 23-year-old predator from the Democratic Republic of Congo, who has flattened two local fighters in the early rounds, said he does not fear Machimana at all.
"He has the skill but I have the ambition. Any boxer that stands in my way, including Machimana, is gonna get hurt," said the superbly fit fighter. He is trained by Kosie Wiese in Gauteng.
"I am appealing for a platform to showcase my potential," Mkwekasa said.
He flattened Bully Maravha in three rounds and Basil Ray in two. His third clash with Mark Strydom ended in the first round when Strydom was disqualified for a deliberate head butt.
Mwekasa will be in action against Nzitu Mbanya at the Benoni Civic Hall on March 16.
The tournament will be staged by Mbali Zantsi of Showtime Promotions.
Mwekasa hopes to meet Osborne after "blowing out" Mbanya.
Machimana has not been busy since he won the title from Anton Nel in April 2005.
His career has failed to take off in the local heavyweight division that has poor quality contenders who will not bring out the best in Machimana.
