Sources - George Kambosos, Devin Haney agree to undisputed lightweight title fight in June

George Kambosos and Devin Haney have struck a deal for a June 5 fight for the undisputed lightweight championship at Marvel Stadium in Melbourne, Australia, sources tell ESPN.

The bout will take place Sunday afternoon in Australia to accommodate a June 4 prime time broadcast in the United States, on ESPN, sources said.

Haney, a rising star from Las Vegas, has competed on DAZN for Eddie Hearn's Matchroom Boxing during his last six fights, but his deal expired. The 23-year-old Haney signed a multi-fight, co-promotional deal with Top Rank and Lou DiBella to fight exclusively on ESPN platforms, sources said.

The deal includes a rematch clause if Haney (27-0, 15 KOs) wins, sources said. In the event Kambosos (20-0, 10 KOs) loses and exercises his right to a return bout, that fight would also take place in his native Australia. Even if Haney loses, his next bout afterward would be co-promoted by Top Rank and DiBella.

Kambosos, who holds all four major sanctioning body titles at 135 pounds, needed an opponent for the first defense of his championship after Vasiliy Lomachenko decided to remain in war-torn Ukraine rather than head to Australia for training camp.

Lomachenko had already agreed to a deal before Russia invaded Ukraine. After officials involved were informed Monday that Lomachekno was out, talks resumed with DAZN for a Kambosos-Haney bout.

DiBella, who promotes Kambosos, couldn't reach a deal with DAZN to stream the bout, so he pivoted back to ESPN, but this time with Haney as the opponent.

Kambosos, 28, defeated Teofimo Lopez in November to capture four titles in ESPN's Upset of the Year. The fight was brutal from the opening bell; Kambosos dropped Lopez in Round 1 but was forced to survive a 10th-round knockdown en
