IBO welterweight champion Isaac Hlatswayo has declared war on Australian Robert Medley in the defence of the title the "Angel" won in May against Joseph Makaringe.
"I will sweat tears and blood," said Hlatswayo who will be under pressure from sceptics who questioned his decision to leave trainer Manny Fernandez for Nick Durandt.
They rate Fernandez highly as a boxing mentor yet they still regard Durandt as the only genuine boxing manager in the country.
Medley, who is undefeated after 18 wins with 12 knockouts, is the stablemate of former IBF junior welterweight champion Lovemore Ndou.
After watching the tape of Medley's victory over Kaizer Mabuza for the IBF Australasian title, Hlatswayo said: "He just cannot beat me. That guy is not a world-class fighter."
Hlatswayo has proved beyond doubt that he is made of sterner stuff. Philip Ndou, Cassius Baloyi, Lucky Lewele and the highly rated American, Nate Campbell, can bear testimony.
They are some of Hlatswayo's 26 victims. It took an unknown Kendall Holt to spoil Hlatswayo's record.
"Nick is working on my strength and you know it's been long since I won on a stoppage," he warned.
His fight with Medley will take place at the Penrith Leagues club in Penrith, New South Wales, Australia, on October 12.
