In Las Vegas, the action continues on Sunday with Zuffa Boxing 02. In the main event, former WBA junior welterweight champion Jose "Rayo" Valenzuela (14-3) kicks off a new chapter in his career as he drops to lightweight to take on hard-hitting Diego "Azabache" Torres over ten rounds. Valenzuela last fought back in March 2025, where he lost his title on the scorecards against Gary Antuanne Russell, but now he's beginning a run towards a new goal under the Zuffa Boxing banner. The southpaw has a 13-1 record against orthodox fighters, and he'll be looking to extend that record on Sunday night when he takes on Torres. From Mexico, Torres heads into the bout on a four-fight win streak following a 2023 loss to current IBF lightweight champion Raymond Muratalla. His 22-1 record boasts 19 knockouts, and the Zapopan, Jalisco native will look to score the biggest win of his career on February 1st.
Serhii Bohachuk vs Radzhab Butaev
In the co-feature, Ukraine's former WBC interim junior middleweight champion Serhii Bohachuk moves up to 160 pounds for a middleweight clash with Russia's Radzhab Butaev. Los Angeles-based Bohachuk quickly built his reputation as a fearsome puncher as he raced to 18-0, with all 18 victories coming inside the distance. But on Sunday night he'll look to bounce back from his unanimous decision loss to Brandon Adams on the Canelo-Crawford undercard last September. Bohachuk has a formidable knockout rate of 92 percent, with 24 of his 26 victories coming inside the distance. He'll look to enhance that knockout record when he takes on Butaev, who bases himself out of Indio, California, and is moving up to 160 pounds for the first time in his career.
Radivoje Kalajdzic vs Oleksandr Gvozdyk
Serbia takes on Ukraine in Zuffa Boxing 02's main card opener scheduled for Sunday, February 1st. Radivoje Kalakdzic takes on ex-WBC champion Oleksandr Gvozdyk (pictured) in a battle between two seasoned light heavyweights with aspirations of championship gold. Serbia's Kalakdzic (29-3, 21 KOs) will end a 541-day layoff when he returns to action at the Meta Apex in Las Vegas, with the Serbian contender keen to re-establish some momentum at 175 pounds. His last outing, back in August 2024, saw Kalakdzic fall to a decision defeat to David Morrell, ending a five-fight win streak. Now he's ready to return, and faces Ukraine's former 175-pound champion. Gvozdyk captured boxing bronze for Ukraine at the London 2012 Olympics before turning pro and knocking out Adonis Stevenson in the eleventh round to capture the light heavyweight world title back 2018 in his sixteenth pro fight. Now standing with a record of 30-2 including the World Series of Boxing, Gvozdyk plans on making another run at championship glory in Zuffa Boxing, starting with victory over former title challenger Kalajdzic on Sunday night.
Jalil Hackett vs Roberto Cruz
Rival 11-1 prospects go head-to-head in the featured preliminary card bout as Washington D.C.'s Jalil Hackett takes on Puerto Rico's Roberto Cruz. Both men turned pro as 18-year olds, but the pair arrive in Las Vegas after taking different routes to get here. While Hackett has stayed active, with his 12 career bouts coming in just over four and a half years, Cruz has built his experience over twice that timespan. Hackett is making a quick turnaround for his Zuffa Boxing debut, just 51 days after his first-round knockout of 29-fight veteran Jose Angulo in December. Cruz, meanwhile, hasn't fought since last May, when he suffered the first defeat of his pro career. Now "El Terror de Cayey" is ready to return, and the Texas-based prospect will look to get back to winning ways against fellow prospect Hackett in their 157-pound catchweight matchup.
Oscar Perez vs Justin Viloria
Unbeaten lightweight southpaws collide as Oscar "El Chato" Perez faces off against Justin "Chosen" Viloria. A Texas native, Perez banked some valuable rounds in 2025 with back-to-back decision wins in eight-round bouts to take his record to 14-0-2 with 7 KOs, while California's Viloria had a fraction more ring time, but in those rounds he managed to secure one decision win and three knockouts as he improved his record to 11-0 with 8 KOs.
Damoni Cato-Cain vs Christian Morales
Damoni Cato-Cain arrives in Vegas looking for a fresh start and a chance to build some new momentum after a two-year, four-fight run that saw one win and one loss bookended by a pair of draws. The most recent of those, against undefeated Jorge Maravillo, came back in December 2024. Now ready to return after a year away from the ring, the 8-1-2 (7 KOs) welterweight will take on more unbeaten opposition in the form of Las Vegas local Christian "El Mejor" Morales (7-0, 7 KOs), who is stepping in to compete on just ten days' notice. His response to getting the short-notice opportunity? "I trust in my skills and said, 'Fuck it. No risk, no reward.'"
Julian Gomez vs Damazion Vanhouter
Heavyweights will step into the Zuffa Boxing ring for the first time as 7-3 Mexican hopeful Julian "La Bomba" Gomez takes on undefeated 10-0 American Damazion Vanhouter. Gomez is looking to bounce back after a knockout defeat to unbeaten Austin Benson last October, while Vanhouter claimed the seventh first-round stoppage win of his career with a TKO of Jose Mario Tamez in December.
Jamar Talley vs Devonte Williams
Opening up Zuffa Boxing 02 is a cruiserweight bout between undefeated Jamar "No Mercy" Talley and Devonte Williams, who has a record of 13 wins, 3 losses, with five knockouts to his name. The Houston native will step through the ropes on Sunday looking to turn around his form after ending a three-and-a-half-year hiatus with back-to-back stoppage losses in 2025. Now the 32-year-old is ready for his first fight in Las Vegas, and an opportunity to transform his fortunes. Standing in his way is unbeaten Talley, a protege of the acclaimed trainer Brian "BoMac" McIntyre and former teammate of the now-retired multi-weight undisputed champion Terence Crawford. The 25-year-old New Jersey native has knocked out four of his five career victories as a pro and has only been beyond the second round once in his career.
