Images shared by Brendan Allen's teammate reveal the middleweight contender was battling a significant staph infection during his fight week at UFC Vegas 122.

Middleweight contender Brendan Allen faced significant adversity leading up to his headline bout against Christian Leroy Duncan at UFC Vegas 122. Following his fifth-round submission victory at the Meta Apex, images surfaced on social media via one of Allen’s teammates showing the fighter dealing with a severe staph infection during fight week.

The photos depict the extent of the skin infection Allen was managing while preparing for the high-stakes main event. Despite the physical setback and the medical challenges associated with such an infection, Allen proceeded with the contest, navigating a grueling five-round battle against the surging Duncan.

Allen’s performance ultimately secured him a late-round finish, highlighting his durability and technical resilience in the cage. While fighters frequently navigate various injuries during training camps, visible evidence of a staph infection is notable due to the risks involved with competition and the potential for rapid skin degradation. Neither the promotion nor Allen’s camp had publicly disclosed the medical issue prior to the imagery being released post-fight. As of now, there has been no word on the severity of the aftermath or the recovery process following his successful, albeit physically demanding, outing.
