Devin Haney and Vasiliy Lomachenko will meet in a huge main event in Las Vegas this evening, as the American defends the undisputed lightweight titles against the Ukrainian. FOLLOW LIVE: Haney vs Lomachenko - latest fight updates The unbeaten Haney, 24, unified the belts against George Kambosos Jr last June, outpointing the Australian in his own backyard before doing so again in October to retain the titles.

In turn, Lopez had stunned Lomachenko with a decision win in 2020 to become unified champion.
