Australian boxer George Kambosos Jr will attempt to win back his world crown in a rematch with American Devin Haney on October 16.
Kambosos surrendered his belts in their unification fight at Marvel Stadium in early June, with Haney declared undisputed lightweight world champion in a unanimous decision.
The Sydneysider has enforced a rematch clause with Haney again travelling to Melbourne for a fight at Rod Laver Arena.
