In his most recent professional outing, the 27-year-old defeated Brian Norman. Haney previously held world titles at lightweight and junior welterweight.
Earlier this year, Haney discussed a potential unification bout with Rolando Romero and a fight with Teofimo Lopez, along with other options. Both matchups ultimately fell through. If Haney signs with Zuffa, he will most likely give up his WBO title.
