Per a report by TMZ Sports, on Sunday, McMillen was rushed to a local hospital after being found unresponsive in the nightclub “Cake” in Scottsdale, AZ. McMillen was reportedly found in the bathroom with a white, powdery substance on the ground near him, prompting responding officers to administer Narcan — an opioid antagonist — before taking him to the hospital, where he was in stable condition upon checking him in. The protege of former bantamweight champion Sean O’Malley, McMillen is one of the breakout stars of the 2025 season of Contender Series, and has already amassed three wins in the UFC, earning a bonus for each one. His action-first style quickly made McMillen a fan favorite, as has the rockstar personality he’s embraced outside of the cage. The 28-year-old most recently defeated Marwan Rahiki at Noche UFC in September, winning Fight of the Night.
