Kambosos, who is four years older than Hitchins at 31, is returning to the venue where he scored his biggest victory, a 2021 split decision over Teofimo Lopez to win three of the four major lightweight titles. Since then, the Sydney, Australia native has gone 2-3, losing a pair of decisions to Devin Haney and suffering an eleventh round stoppage against Vasyl Lomachenko, but rebounded in his junior welterweight debut in March, winning a unanimous decision over Jake Wyllie in Sydney.
