GEORGE KAMBOSOS JR. has a new weight class and a new co-promoter.

Boxing News has learned that Eddie Hearn’s Matchroom Boxing has partnered with DiBella Entertainment, Kambosos’ longtime promoter, to represent the former unified lightweight champion. Australia’s Kambosos is expected to move up to the super lightweight division for his next fight as well, which will take place on an undetermined date in February at an Australian site to be chosen in Brisbane or Gold Coast.

Montreal’s Mathieu Germain, 25-2-1 (10 KOs), is the front-runner to box Kambosos next in the main event of a card DAZN is expected to stream worldwide. Kambosos, 21-3 (10 KOs), last competed on May 12, when three-division champion Vasiliy Lomachenko, 18-3 (12 KOs), stopped him in the 11^th round of their fight for the then-vacant IBF lightweight title at RAC Arena in Perth, Australia.

The 31-year-old Kambosos is 1-3 in his past four fights, including back-to-back lopsided points losses to former undisputed lightweight champ Devin Haney in 2022.

Sydney’s Kambosos nonetheless remains a marketable boxer in Australia. Hearn therefore could help arrange an all-Australia showdown between Kambosos and Liam Paro if Brisbane’s Paro, 25-0 (15 KOs), successfully defends his IBF super lightweight title against mandatory challenger Richardson Hitchins, 18-0 (7 KOs), on December 7 at Roberto Clemente Coliseum in San Juan, Puerto Rico, and Kambosos wins his upcoming match.

In addition to co-promoting Kambosos, Matchroom represents Paro and New York’s Hitchins, the mandatory challenger for Paro’s championship.

Though the date and site hadn’t been solidified as of Thursday morning, Boxing News has also confirmed that the card Kambosos is set to headline in February will also include two women’s world championship matches. In one of those bouts, Australian southpaw Skye Nicholson, 12-0 (1 KO), will make a mandated defence of her WBC featherweight title against American Tiara Brown, 17-0 (11 KOs), of Lehigh Acres, Florida.

England’s Nina Hughes, 6-1 (2 KOs), will also attempt to avenge her controversial 10-round, majority-decision defeat to Australia’s Cherneka Johnson, 16-2 (6 KOs), on the same night as the Nicholson-Brown bout. Johnson won the WBA bantamweight title from Hughes on the Lomachenko-Kambosos undercard.
