Undisputed lightweight champion Devin Haney defends his titles against Vasiliy Lomachenko in a blockbuster bout this weekend. American Haney unified the belts against George Kambosos Jr last June in the Australian’s home country, before returning to Kambosos’ backyard to retain the titles in a rematch in October. On both occasions, the unbeaten Haney – who is still just 24 – clinically outboxed his opponent, who was previously undefeated and had taken three of the belts from Teofimo Lopez in 2021. Prior to that, Lopez handed Lomachenko a surprising points defeat in 2020 to become unified champion, but the Ukrainian has responded with three straight wins to set up this fight with Haney in Las Vegas. At 35, Lomachenko could be running out of time to become a world champion again, and as impressive as the southpaw’s career has been, he faces a stiff test in Haney. Here’s all you need to know. When is it? The fight will take place at the T-Mobile Arena in Las Vegas on Saturday 20 May. The main card is due to begin at 1am BST on Sunday 21 May (5pm PT, 7pm CT, 8pm ET), with ring walks for the main event expected at approximately 4am BST (8pm PT, 10pm CT, 11pm ET).
