Undefeated UFC featherweight Tommy McMillen was hospitalized Sunday after police administered Narcan to him at a Scottsdale nightclub.

Authorities responded to a call at Cake, a nightclub in Old Town Scottsdale, where they found the 28-year-old fighter unresponsive in a bathroom. Officers administered Narcan, a medication used to reverse opioid overdoses, after observing a white, powdery substance on the floor near McMillen.

McMillen was transported to a local hospital, where his condition was not deemed life-threatening.

The fighter, who trains in Glendale, Arizona, holds a professional record of 12-0. He has a 3-0 record in the UFC since his debut in April, most recently winning a unanimous decision on September 12. He secured a UFC contract after a split decision win on Dana White's Contender Series.
