Lee Selby’s world title eliminator against George Kambosos Jr will be on October 31, on the Derek Chisora vs Oleksandr Usyk undercard, live on Sky Sports Box Office.
The winner will become the mandatory challenger to the IBF lightweight title, which Teofimo Lopez will defend in a unification battle with Vasiliy Lomachenko next month.
Welshman Selby is a former IBF featherweight champion plotting a route to a world title in a higher division.
Australia’s Kambosos Jr is undefeated in 18 with 10 stoppages.
Selby (28-2, 9 KOs) edged out Scottish legend Ricky Burns via a majority decision at The O2 in London last October to stay in line for another world title shot and now finds himself within touching distance of becoming a two-weight world champion.
“I’m delighted that Eddie Hearn and Matchroom Boxing have managed to get this fight on again,” said Selby.
“I’m one step away from a shot at the IBF lightweight title and my dream of becoming Wales’ first ever two-weight world champion.
“Kambosos Jr is a hungry young fighter that I know will bring it all, but I’ve had some of my best performances against Australian boxers stopping both Corey McConnell and Joel Brunker in title fights and October 31 will be no different.”
