Belal Muhammad and Gabriel Bonfim successfully completed official weigh-ins Friday for their main event bout at UFC Fight Night 278 [1].

The successful weigh-ins ensure that the headline fight will proceed as scheduled without the delays or financial penalties associated with missing weight. This step is critical for fighter health and competitive fairness in the welterweight division.

The proceedings took place June 5, 2026, in Las Vegas, Nevada, at the Meta APEX facility [2]. Both fighters were required to meet the specific weight limits to qualify for the contest [3].

Belal Muhammad weighed in at 170.5 lbs [4]. Muhammad said the process was easy on social media following the official scale reading [4].

Gabriel Bonfim also met the requirements to compete in the main event [1]. The event, known as UFC Vegas 118, features a full card of athletes who underwent final face-offs before the competition [5].

"Belal Muhammad, Gabriel Bonfim clash in UFC main event," MMAjunkie said [6].

The Meta APEX has served as a frequent hub for UFC Fight Night events, providing a controlled environment for both the weigh-ins and the bouts. By hitting the mark, both athletes avoid the possibility of the fight being downgraded to a catchweight contest or canceled entirely [3].

The successful weigh-ins for UFC Fight Night 278 remove the final administrative hurdle before the bout. In mixed martial arts, missing weight can lead to a fighter forfeiting a percentage of their purse or the fight being scrapped, meaning the stability of this card is now confirmed for the promoter and the athletes.
