Brendan Allen Competed at UFC Vegas 122 While Dealing With Staph Infection

Following his fifth-round rear-naked choke victory against Christian Leroy Duncan on October 10, 2026, Brendan Allen’s teammate Belal Muhammad revealed the fighter’s undisclosed health struggles. Muhammad stated that Allen had been dealing with a staph infection since the Tuesday of fight week and was required to take antibiotics.

Despite the diagnosis, Allen proceeded with the middleweight main event at the Meta APEX in Las Vegas. The win marked Allen's fourth consecutive victory and brought an end to Duncan’s five-fight win streak. Muhammad commended the effort, noting that Allen completed the fight while still needing five more days of antibiotic treatment.
