LAS VEGAS — Mixed martial arts competition often tests an athlete’s physical conditioning, mental fortitude, and technical mastery. However, the unseen battles that take place long before fighters step into the Octagon frequently define their true character. Such was the case for middleweight contender Brendan Allen, who successfully navigated a severe health hurdle during fight week to secure a statement victory inside the Ultimate Fighting Championship.
According to his teammate and former UFC welterweight champion Belal Muhammad, Allen was quietly battling a staph infection in the days leading up to his headlining matchup against Christian Leroy Duncan. The high-stakes main event took place at UFC Vegas 122 on Saturday at the UFC Apex facility in Las Vegas, Nevada. Despite the physical toll of the bacterial infection and the regimen of medical treatments required to keep it under control, Allen pressed forward to deliver a memorable performance.
The victory not only extended Allen’s current winning streak but also solidified his standing among the elite contenders in the UFC’s talent-rich middleweight division. Yet, the path to the championship rounds was fraught with obstacles that few outside of his immediate training camp could have imagined.
Belal Muhammad Details Allen’s Fight-Week Illness Before Duncan Submission
The full extent of Allen’s pre-fight adversity did not come to light until after the final bell sounded. Taking to social media to shed light on the behind-the-scenes struggles, Muhammad revealed that Allen’s health complications began days before the cage doors closed.
According to Muhammad, the infection surfaced on Tuesday of fight week, forcing medical personnel to intervene and prescribe a heavy course of antibiotics. Even as he stepped onto the scale, completed media obligations, and prepared to face a dangerous striker like Duncan, Allen was dealing with the systemic effects of the infection. In fact, Muhammad noted that Allen still had five days remaining on his prescribed course of antibiotics long after the event had concluded.
"What people don’t know is Brendan was dealing with a staph infection since Tuesday of fight week," Muhammad wrote in a post published on the social media platform X. "Had to get on antibiotics, still has 5 days left on them, and despite all that adversity, went out there and got the finish. Never complained, never made excuses, just found a way to win. That’s the heart of a champion. Proud of my brother."
The transparency from Muhammad highlighted the unique pressures and physical hardships professional fighters endure. Staph infections are a persistent hazard in combat sports training camps due to close skin-to-skin contact and mat surfaces. When contracted during fight week, they can severely drain an athlete’s energy, compromise their immune system, and complicate the already delicate process of weight cutting.
Despite these compounding factors, Allen elected to push through the discomfort rather than withdraw from the main event spot. His resilience ultimately paid dividends in the cage, where he showcased both his championship aspirations and his tactical adaptability over the course of five scheduled rounds.
In the main event matchup, Allen (28-7) faced a formidable challenge in Christian Leroy Duncan (15-3), an explosive striker known for his dynamic movement and finishing ability. The bout served as a crucial test for both athletes looking to make waves in the upper tier of the middleweight weight class.
As the fight progressed into the championship rounds, fatigue naturally became a factor for both competitors. However, Allen’s grappling pedigree and veteran composure began to dictate the pace of the contest. In the fifth and final round, Allen secured the opening he needed, capitalizing on a positional scramble to lock in a rear-naked choke. Duncan was forced to tap out, handing Allen a dramatic submission victory with moments to spare.
The win marked Allen’s fourth consecutive victory inside the Octagon, reinforcing his trajectory toward a potential championship opportunity. His ability to weather both Duncan’s offensive threats and his own physical ailments did not go unnoticed by the promotion’s executives. Following the conclusion of the event, Allen was awarded a well-deserved Performance of the Night bonus for his late-fight submission finish.
With the victory secured and his winning streak extended, Allen immediately turned his attention toward the future of the division. During his post-fight interview inside the Octagon, the surging middleweight contender seized the microphone to call out former divisional champion Dricus du Plessis for his next promotional appearance, signaling his intent to challenge the very top of the weight class as he continues his march toward championship gold.
