Lomachenko and Kambosos will compete for the vacant IBF lightweight title.
In December, Haney, the former undisputed champ at 135, moved up to 140 to challenge Regis Prograis for the WBC super lightweight title. “The Dream” won impressively, claiming a lopsided unanimous decision in San Francisco.
Haney ultimately relinquished all of his lightweight titles, which freed up the IBF crown that will be on the line between Lomachenko and Kambosos.
