The stage is officially set for an explosive weekend of mixed martial arts action as the combatants for UFC Vegas 123 successfully stepped onto the scale on Friday morning. Headlining the 12-fight card is a high-stakes, five-round lightweight showdown between fan-favorite veteran Renato "Money Moicano" Carneiro and surging Australian prospect Tom "Big Train" Nolan. With both main event athletes making weight without issue, the card is locked in and ready to deliver fireworks for fans tuning in live from the UFC APEX.
The official weigh-in proceedings, which took place in the morning ahead of the weekend event, went smoothly for the vast majority of the fighters. Carneiro, known just as much for his charismatic microphone skills as his elite grappling and striking inside the cage, weighed in right on the championship limit at 156 pounds. Across the division, his opponent, Nolan, tipped the scale at 155.5 pounds, comfortably making weight for what marks the biggest opportunity of his professional mixed martial arts career thus far.
Out of the entire 12-fight lineup, only one blemish marred an otherwise flawless morning on the scales. Featherweight competitor Francis Marshall came in two pounds heavy, registering at 148 pounds for his scheduled bout against Dakota Hope, who successfully made weight at 145.5 pounds. As per standard athletic commission and promotional protocol, Marshall will forfeit a predetermined percentage of his fight purse to Hope, but the bout will proceed as planned. Every other fighter on the card safely made their contracted weight limits, ensuring a full and competitive night of fights.
The Veteran Gatekeeper Battles the Rising Tide
For the 37-year-old Renato Carneiro, Saturday night represents a crucial juncture in his storied career. Holding a professional record of 21 wins, 7 losses, and 1 draw, the Brazilian veteran enters the Octagon riding the momentum of a dominant submission victory over Chris Duncan. That impressive win marked Carneiro’s first victory of the calendar year and served as a stark reminder of his dangerous capabilities on the canvas.
However, time waits for no man in the ultra-competitive lightweight division. As an established veteran who has shared the Octagon with some of the biggest names in the sport, Carneiro finds himself in the familiar yet dangerous position of defending his ranking against the organization’s hungriest up-and-comers. With a win on Saturday, "Moicano" aims to silence any lingering doubts about his longevity at the highest level and prove to the matchmaking brass that he remains a legitimate title threat rather than a mere stepping stone for the next generation. Weighing in precisely at 156 pounds, the Brazilian looked focused and ready to handle the rigorous five-round pace demanded by a main event assignment.
Standing on the opposite side of the Octagon will be Tom Nolan, a 26-year-old powerhouse eager to cement his arrival in the upper echelons of the UFC lightweight division. Nolan, carrying an impressive 11-1 professional record, has bounced back in spectacular fashion since suffering the lone defeat of his career in early 2024. Nicknamed "Big Train," the Australian has since rattled off five consecutive victories, showcasing devastating knockout power and a well-rounded skill set that has caught the attention of the promotion’s matchmakers.
Nolan’s ascent reached a notable peak earlier this year when he secured a hard-fought unanimous decision victory over Fares Ziam, proving he can grind out tough wins against elite competition. Now, stepping into his very first UFC main event, Nolan has a golden opportunity to leapfrog the rankings by taking out a divisional mainstay. Weighing in at 155.5 pounds, the young contender looked sharp and composed during the weigh-ins, ready to capitalize on the biggest spotlight of his career.
