Devin Haney vs George Kambosos Jr: Everything you need to know ahead of title epic

Australia’s George Kambosos Jr and American Devin Haney will do battle in Melbourne on Sunday in what is being billed as the biggest fight in Australian boxing history.

It’s undefeated champion versus undefeated champion in the first lightweight division unification match in over three decades.

Kambosos (20-0, 10 KO) will be putting his WBA (Super), IBF and WBO lightweight titles on the line, as well as The Ring magazine lightweight belt, while Haney (27-0, 15 KO) is putting up his WBC lightweight strap.

As a result, one man will emerge from the packed-out Marvel Stadium as the first undisputed lightweight champion since Pernell Whitaker in 1990, and the first in the four-belt era.

Kambosos catapulted himself onto the global stage last November when he caused one of the biggest upsets of recent times by defeating Teofimo Lopez via split decision in the Hulu Theater at New York’s world famous Madison Square Garden, to clinch all of his belts.

Kambosos headed into that fight as a $7 rank outsider, and emerged as a world champion.

Meanwhile, Haney has successfully defended his title four times in a row against Alfredo Santiago, Yuriorkis Gamboa, Jorge Linares and Joseph Diaz.

This highly-anticipated event will mark the first time Kambosos fights on home soil in five years, having fought his last seven fights abroad.

WHEN DOES IT START The boxing action begins at 9.05am AEST on Sunday with live coverage on Fox Sports from 9.30am AEST. The main card, available via Main Event, is scheduled to commence at 11am with Kambosos v Haney expected to start sometime after 1pm.
