Local welterweight Joaquin Buckley welcomes Nursulton Ruziboev to the division in the co-main event of the evening.

Buckley has been sharp since relocating to the 170-pound ranks at the start of last year, posting three wins in as many starts. He forced his way into the rankings with a second-round stoppage win over Vicente Luque at the end of March, and will now look to defend his position at home in front of a partisan crowd at Enterprise Center.

Ruziboev has needed just under five minutes combined to register a pair of victories to begin his UFC tenure, joining Buckley in collecting a stoppage win on that Atlantic City card at the end of March. He’s won 10 straight overall — all by stoppage — and looks to add to that streak in his highest profile fight to date on Saturday night in St. Louis.

While Buckley always seemed better suited for life in the 170-pound ranks, it’s going to be interesting to see how Ruziboev does transitioning to the weight class, as he’s massive for the division at six-foot-five. Will “New Mansa” send the locals home happy or can the Philadelphia-based fighter register a third straight stoppage win inside the Octagon?

Alonzo Menifield vs Carlos Ulberg

Originally penciled in to compete earlier in the year, powerful light heavyweights Alonzo Menifield and Carlos Ulberg will finally face off here.

The 36-year-old Menifield arrives on a five-fight unbeaten streak, sandwiching a pair of wins on either side of his grueling draw with Jimmy Crute at UFC 284. A member of the Dana White’s Contender Series (DWCS) Class of ’18, Menifield has gone 6-1-1 over his last eight starts, showing improvements across the board while maintaining his ever-present power.

Ulberg was two years behind Menifield in graduating from the Contender Series, and after stumbling out of the gate against Kennedy Nzechuwku, the City Kickboxing man has put together a five-fight winning streak with each of his last four wins coming by stoppage. Last time out, “Black Jag” earned a third-round submission win over Da-un Jung, showcasing another side of his game to move to 10-1 overall.

Diego Ferreira vs Mateusz Rebecki

Alex Caceres looks to get things moving in the right direction again, while local product Sean Woodson aims to give the Missouri faithful something to cheer about early in the main card.

Year 14 on the roster commences for Caceres with the TUF alum looking to bounce back after suffering a unanimous decision defeat in an entertaining, competitive bout with Giga Chikadze last August in Singapore. He had won seven of eight before that contest and remains a formidable test for anyone looking to break into the Top 15 in the featherweight division.

FREE FIGHT: Joaquin Buckley vs Vicente Luque

After punching his ticket to the UFC roster with a knockout win over Terrance McKinney on Season 3 of Dana White’s Contender Series, Woodson has built a 5-1-1 record through his first seven UFC starts. He enters off a split decision win over Charles Jourdain in January, and could potentially break into the rankings with another big effort on Saturday.

This is going to be a fascinating battle between two men that like to use their range, but attack with different weapons. Caceres throws a lot more kicks than Woodson, who prefers to box, so it will be interesting to see who is able to set the tone early and how the other adjusts over the course of the contest.

Waldo Cortes Acosta vs Robelis Despaigne

Heavyweights close out the main card and heavyweights open the main card as Waldo Cortes Acosta faces off with Robelis Despaigne.

“Salsa Boy” has put together a 4-1 record through his first five UFC appearances, most recently collecting a unanimous decision win over Andrei Arlovski on the year’s opening event. The 32-year-old is still developing, but there have been positive flashes the whole way through, and a victory on Saturday could expedite his climb in the heavyweight ranks.

Despaigne won his UFC debut earlier this year in 18 seconds, which was somehow the second longest fight of his five-fight MMA career. The 35-year-old Olympic bronze medalist in taekwondo is a captivating addition to the division, and how he does against Cortes Acosta will help illustrate what the next 12 months may hold for the speedy finisher going forward.

Can Cortes Acosta drag Despaigne into deeper water or will “The Big Boy” continue to bounce his opponents in expeditious fashion?

Preliminary Card Matchups

Chase Hooper vs Viacheslav Borshchev

DWCS alums Chase Hooper and Viacheslav Borshchev share the Octagon in the final preliminary card fight of the evening.

Now 24, Hooper has grown into his wiry frame and started to put things together more, having gone 2-0 since relocating to the lightweight ranks. “Slava Claus” has gone 2-2-1 over his first five UFC starts, entering off a majority draw with Nazim Sadykhov at UFC 295 in November.

Terrance McKinney vs Esteban Ribovics

Lightweights Terrance McKinney and Esteban Ribovics face off in a battle of promising talents looking to take a big step forward in 2024.

McKinney fought four times last year, dropping the first two before registering quick finishes over Mike Breeden and Brendan Marotte to close out the year on a high. Ribovics dropped his promotional debut in March but rebounded with a good win over Kamuela Kirk in July to move to 12-1 overall.

Tabatha Ricci vs Tecia Pennington

Tabatha Ricci and Tecia Pennington share the Octagon in an intriguing strawweight battle on Saturday’s prelims.

Ricci suffered her first loss in the UFC’s 115-pound weight class in her last outing, landing on the wrong side of a split decision in her UFC 295 bout with Loopy Godinez. Pennington competes for the first time in just over two years, looking to re-establish herself as the Top 15 mainstay she was before pressing pause on her career in order to welcome her first child with her wife, UFC bantamweight champ Raquel Pennington.

Billy Goff vs Trey Waters

DWCS alums Billy Goff and Trey Waters meet in what should be an exciting clash early in the evening.

The 25-year-old Goff is a proven finisher with a penchant for getting touched up early, having rallied to earn first-round stoppages in both his Contender Series victory and UFC debut. Waters lost in his appearance on the annual talent search series but made the most of a short-notice opportunity last April, out-hustling Josh Quinlan to earn his first UFC win.

Charles Johnson vs Jake Hadley

St. Louis native Charles Johnson welcomes Jake Hadley to his hometown in this flyweight fixture.

One of the most active fighters in the division since arriving in the UFC, Johnson makes his eighth start in less than two years, looking to build off his decision win over Azat Maksum in February. Hadley has gone 2-2 to begin his UFC tenure, earning a pair of finishes in between decision defeats to Allan Nascimento and, most recently, Cody Durden.

Jared Gooden vs Kevin Jousset

Jared Gooden and Kevin Jousset share the Octagon in this battle of welterweights aiming to build on recent successes.

Gooden submitted Wellington Turman in December, getting things moving in the right direction again after missing weight in the first start of his second tour of duty with the promotion. Another member of the City Kickboxing crew, Jousset has posted back-to-back wins to begin his UFC run, most recently outworking Song Kenan towards the end of last year.

JJ Aldrich vs Veronica Hardy

Saturday’s action in St. Louis opens in the flyweight division, as JJ Aldrich and Veronica each go in search of a third consecutive victory.

The 31-year-old Aldrich rebounded from an early 2023 loss to Ariane Da Silva with consecutive wins over Liang Na and Montana De La Rosa to move to 5-2 over her previous seven starts. Hardy returned for the first time in three years last March, getting the better of Juliana Miller before edging out Jamey-Lyn Horth in December to move to 8-4-1 overall for her career.
