Emperors Palace, Kempton Park, South Africa - In a showdown for the vacant International Boxing Organization (IBO) welterweight title, Thulani Mbenge (14-0, 11 KOs) picked up the biggest win of his career with a seventh round stoppage of feared veteran Diego Chaves (26-4-1, 22 KOs).

Mgenge landed a big right hand that sent Chaves down in the sixth round.

He followed that up in the seventh, by landing the same punch on Chaves to close the show.

In March of this year, Mgenge won a twelve round unanimous decision over Diego Cruz to capture the vacant WBC International welterweight title.

Chaves had been inactive since December of 2017, when he was knocked out in three rounds by Jamal James.
