This Saturday, August 2, 2025, the Ultimate Fighting Championship (UFC) returns to the UFC Apex in Las Vegas, Nevada, for UFC Vegas 108. The card lost its top-ranked matchup just days before the event, leaving fans with bouts exclusively between Bantamweight and Welterweight fighters, making for an intriguing night of competition. This article provides detailed UFC Vegas 108 fight predictions for the five main card bouts.
Lightweight Clash Featuring Mateusz Rebecki and Chris Duncan
In the co-main event, Polish fighter Mateusz Rebecki (-218) faces off against American Chris Duncan (+180), with both men bringing contrasting styles. Rebecki, a seasoned 32-year-old with a solid background in striking, wrestling, and Brazilian jiu-jitsu, aims to build on his recent victory. Duncan comes in riding a two-fight winning streak and is known for his aggressive striking and unexpected submission skills.
Rebecki thrives with a precise counter left hand and strong wrestling abilities, which may negate Duncan’s aggressive offense and submission attempts, such as the guillotine choke. Duncan’s unpredictable grappling could challenge Rebecki, but the Polish fighter’s balanced skill set should control the match. The key question remains whether Rebecki can secure a finish.
Prediction: Rebecki is favored to win by submission.
Lightweight Bout: Esteban Ribovics Versus Elves Brenner
Esteban Ribovics (-258) and Elves Brenner (+210) meet in another lightweight matchup full of pace and aggression. Ribovics lost his last fight but is known for his high-volume, tight kickboxing and resilience, often compensating for reach disadvantages with relentless combinations. Brenner, a teammate of Charles Oliveira and practitioner of the aggressive Chute Boxe style, brings power and dangerous submission threats, though he has suffered consecutive defeats recently.
The fight promises a striking battle where speed and precision will play vital roles. Ribovics’ quicker hands are expected to give him the edge early, helping him dictate distance and tempo. Brenner’s power and submission skills add complexity, but Ribovics’ ability to manage range and maintain pressure should prevail.
Prediction: Ribovics is expected to claim victory by decision.
Women’s Bantamweight Matchup Between Karol Rosa and Nora Cornolle
In a ranked Women’s Bantamweight contest, Karol Rosa (-192) takes on Nora Cornolle (+160), who has shown a recent bounce back after a prior loss. Rosa is a tough fighter who presses forward, combining striking with clinch work, while Cornolle, a French Muay Thai champion adapting to MMA, prefers striking at distance and thrives on precise counterattacks.
Cornolle’s background gives her the ability to punish aggressive advances through measured strikes like linear kicks and knees, which could limit Rosa’s effectiveness. Rosa’s cage control and clinch are strengths, but Cornolle’s clean striking and movement may frustrate her opponent and secure a tactical edge over the course of the bout.
Prediction: Cornolle is favored to win via decision.
Welterweight Battle: Neil Magny Against Elizeu Zaleski
Veterans Neil Magny (+170) and Elizeu Zaleski (-205) collide in a welterweight matchup featuring fighters with contrasting recent results. Magny has lost two consecutive fights and struggles particularly with calf kicks, a key strike in modern MMA, while Zaleski, though less battle-tested against top-tier competition lately, remains a dynamic striker known for his Capoeira kicks and heavy punches.
Magny’s strategy now relies heavily on clinch work and grappling control due to declining striking efficiency, and he must withstand Zaleski’s early assault to take over as the fight progresses. Zaleski’s striking will likely lose power in later rounds, while Magny’s toughness and grappling could turn the tide.
Prediction: Magny is projected to win by decision after surviving the initial storm.
Featherweight Showdown: Kevin Vallejos Versus Danny Silva
Young prospect Kevin Vallejos (-455) returns following a successful UFC debut, facing off against Danny Silva (+350), who has earned two Octagon wins. Vallejos, praised for his boxing skills echoing Ilia Topuria’s style, combines fluid combinations and accurate power punches. Silva is a competent boxer with strong defense and effective calf kicks, and he benefits from significant height and reach advantages.
The fight is expected to center on striking, with Silva aiming to capitalize on his physical attributes and target Vallejos’ lead leg to slow him down. However, Vallejos’ speed and power are thought to be too much for Silva, marking Vallejos as a rising contender with a bright future.
Prediction: Vallejos is likely to earn a decision victory, continuing his momentum.
Overall Impact and What to Expect from UFC Vegas 108
Although the card lost its top-ranked main event, UFC Vegas 108 still presents compelling matchups mainly between Bantamweight and Welterweight fighters who combine technical skill with aggressive strategies. The fight predictions lean towards experienced favorites continuing to assert dominance, but a few underdogs with submission skills and striking versatility pose credible threats.
The event will test whether rising prospects can maintain their trajectories or if established veterans will impose control. Fans should expect an intense night of action, with several bouts likely to influence rankings within these competitive divisions. As the UFC continues to develop talent and entertain audiences, this event will contribute key markers for the fighters’ careers heading deeper into 2025.
