A challenger has a chance to upstage the champion, because he is hungrier, acknowledges boxing trainer Peter ''The Black Chinese" Shakung.
But it's not a given that it will happen, he said.
The mentor from Diepkloof, Soweto, was referring to the upcoming South African junior middleweight women's championship between his charge, Esther ''The Dazzler" Mashiya, and Liz Butler.
Their fight, scheduled for 10 rounds, will take place at Adelaide Tambo Hall in Middelburg, Mpumalanga, at 7.30pm on Saturday.
Mashiya - who hails from Tweefontein in Mpumalanga, now based in Alexandra, Joburg - will bid for the third defence.
The bout will be organised by Mxolisi Gumede of Ethembeni Promotions and the Mpumalanga provincial government.
