Sivenathi Nontshinga

He is a two-time IBF light-flyweight world champion, having held the belt from 2022 to November 2023 in his first reign, and since February 2024 in his second reign. He has previously held the IBF International light-flyweight title from 2019 to 2022. Also a former African light-flyweight champion, he is ranked as the world's fifth-best active light-flyweight by BoxRec and the seventh-best by the IBF.

Nontshinga was raised in Newlands, a "chicken farm community" located at the entrance to Mdantsane township in Eastern Cape. His father, Thembani Gopheni, is his trainer and his handler.

Early career

Nontshinga made his professional debut on 30 July 2017 at the age of 18, defeating Sandile Wessels in a third-round finish in East London. After four stoppages in his first four fights, he was soon recognized as a promising teen sensation in South Africa. In only his fifth pro fight, he defeated Tisetso Modisadife for the vacant African light-flyweight title.

On 7 April 2019, he scored a first-round knockout over Adam Yahaya to win the vacant IBF International light-flyweight title in Port Elizabeth. In his first title defense, Nontshinga defeated compatriot Siyabonga Siyo, a fighter he idolised growing up. He finished Siyo with a barrage of blows in the ninth round to make it eighth stoppage wins in eighth fights. He retained his belt again on 8 March 2020 by defeating Ivan Soriano, ranked number 5 by the IBF, at the Orient Theatre in East London. Nontshinga suffered a swollen left eye early, but after knocking him down at the end of the fourth round, he dropped the veteran for good in the fifth with a right cross.

After more than a year without a fight due to the COVID-19 pandemic, Nontshinga defeated Filipino prospect Christian Araneta in an IBF title eliminator in Port Elizabeth on 24 April 2021. Although he was knocked down in the 12th round, he was favored unanimously on the judges' scorecards (115–112, 114–113, 114–113).
