Errol Spence Jr vs Tim Tszyu event set for Sydney with Charlo, Fulton on undercard

"

LAS VEGAS, NEVADA - MAY 31: Jermall Charlo poses with referee Mark Nelson after defeating LaManna in a super middleweight bout at Michelob ULTRA Arena on May 31, 2025 in Las Vegas, Nevada. Charlo won by TKO after the fifth round when a ringside physician advised LaManna should not continue.

Fighting for just the third time in the last five years, Jermall Charlo (34-0, 23 KO) returns for what might be the biggest mismatch of his career against super welterweight Koen Mazoudier (15-4-1, 6 KO). New South Wales’ “S.O.G.” (not that one) sports a 2024 stoppage loss to Nikita Tszyu and no wins of note, putting him on a tier below even the likes of Jose Benavidez Jr and “Cornflake” LaManna. Not exactly the sort of matchup you’d envision for a 36-year-old who could probably ride his name recognition and sanctioning body clout to a title shot. In slightly more palatable news, Stephen Fulton (23-2, 8 KO) looks to bounce back from humiliation against Liam Wilson (18-3, 10 KO). “Cool Boy Steph” has a lot to prove after missing weight and stinking out the joint in last December’s title bid against O’Shaquie Foster, and though Wilson has shown himself to be a step below the division’s elite, he’s good enough to give us an idea of whether Fulton has any sort of future at 130.
