"To be the IBF champion proved that I was up there among the best because you know that we did not command such respect as WBU champions because it was not rated among the top-four most respected boxing bodies," said the man who co-promotes boxing with Joyce Kungwane under the banner of TLB Boxing Promotions.
The other sanctioning boxing bodies he is referring to are the WBA, WBC and WBO.
Sadly, Ledwaba's trainer David Kgotsane did not live to enjoy the fruits of his hard work.
He died from lung ailments three weeks before Ledwaba's first defence against Edison Valencia Diaz in the US. Ledwaba dedicated his stoppage win to his fallen mentor.
"His passing on affected me badly. It seemed he felt he was going to die because he gave us training guides and said to me whatever happens to him I must continue with my title defence," said Ledwaba, who roped in respected trainer Mzimasi Mnguni in his corner to assist Tshidiso Manamathela, who was Kgotsane's assistant.
After six more fights, including two defeats to Cassius Baloyi, Ledwaba retired and started training fighters.
"I have gone back to training fighters," said Ledwaba.
