Edinburgh’s Steve Simmons continued his impressive start to the World Championships with a second-round victory over Australia's Mostyn Niemann.

Simmons opened his account by defeating Kenya's Elly Ajowi 13-3 before overhauling Niemann and will now face European light heavyweight Oleksandr Usyk on Tuesday.

The Leith heavyweight held a three-point lead going into the final round against Niemann before a powerful late finish saw him win 11-4.

"I just dominated him from the opening bell with stiff jabs and left hooks," said Simmons.

"This Ukranian guy Usyk competed in the last Olympic games at heavyweight and I've been warned that he is very useful but I am very confident after winning my first two bouts."

And Great Britain team coach Kelvyn Travis admits Usyk will provide Simmons with his toughest test to date.

"This will be an difficult test for Simmons but I'm confident that Steve will go all out to give Usyk a tough scrap on Tuesday," said Travis.

"While it's true that Simmons was too good for Niemann he nevertheless gave a convincing and commanding performance against a gritty opponent. I was very pleased by his showing."
