Brendan Allen was dealing with a significant amount of adversity well before he ever stepped foot inside the Octagon this past Saturday night in Las Vegas. The high stakes of a main event bout at the Meta APEX were already enough to test any elite athlete, but Allen’s journey to fight night involved a physical hurdle that remained hidden from the public until after the dust had settled.
Headlining the UFC Vegas 122 card, Allen faced off against fellow surging middleweight contender Christian Leroy Duncan in what turned out to be a grueling, high-level test for both men. In a back-and-forth battle that pushed deep into championship rounds, Allen ultimately prevailed, locking in a rear-naked choke submission in the fifth round. The victory not only extended his impressive winning streak to four consecutive fights but also solidified his standing as a major force in the ultra-competitive UFC middleweight division.
However, viewers tuning into the broadcast noticed that there were stretches during the contest where Allen appeared uncharacteristically sluggish, at times looking like he struggled to find his rhythm or get out of first gear. The heavy-footed movement and moments of visible fatigue raised questions among analysts and fans alike, given Allen’s usual high-pace output.
Those questions were soon answered by Allen’s teammate, friend, and fellow elite UFC competitor, Belal Muhammad. Taking to social media shortly after the event, Muhammad shed light on the unseen physical battle Allen had been fighting all week long, revealing that the middleweight contender had entered fight week battling a gnarly staph infection and was forced to compete while heavily medicated on antibiotics.
Muhammad shared the behind-the-scenes details on social media alongside visual evidence of the infection, highlighting the extent of the physical toll Allen was managing. "What people don’t know is Brendan was dealing with a staph infection since Tuesday of fight week," Muhammad wrote. "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."
Staph infections are notoriously debilitating for combat athletes, often causing severe fatigue, localized pain, tissue swelling, and systemic weakness, especially when combined with the severe physical strain of making weight and preparing for a twenty-five-minute martial arts contest. The fact that Allen managed to not only survive five hard rounds against a dangerous opponent like Duncan, but actively hunt for and secure a late-game submission finish under those clinical conditions, underscores the extraordinary resilience required to compete at the highest level of mixed martial arts.
For Christian Leroy Duncan, the main event defeat marked the painful end of a strong five-fight winning streak. The English middleweight put on a highly competitive and game showing in what was his first-ever UFC main event assignment, proving that he belongs among the elite tier of the division despite falling short in the final moments of the fight. The clash showcased Duncan’s dynamic striking and ability to challenge a top-tier grappler, but Allen’s veteran savvy and championship endurance eventually proved to be the deciding factors as the bout reached its climax in the final frame.
With his hand raised and his winning streak extended, Allen immediately turned his attention toward the future of the division. Seizing the microphone after his gritty performance, the victor wasted no time in calling out former middleweight champion Dricus du Plessis, signaling his intent to target the very top of the weight class as he continues his march toward a potential world title opportunity.
As Allen looks ahead to his next potential matchup and works through the remainder of his antibiotic regimen to fully recover from the grueling week, his performance at UFC Vegas 122 will long be remembered not just for the submission finish, but for the unseen grit and determination it took to reach the finish line.
