Demetrious “Mighty Mouse” Johnson is calling it a career.
The former UFC flyweight champion, current ONE Championship flyweight champion and arguably one of the greatest mixed martial artists of all time announced Friday night at ONE 168 in Denver that he will be hanging up the gloves.
Johnson, 38, retires with a professional MMA record of 25-4-1 and leaves behind a decorated legacy in which he is widely recognized as the best to ever compete in the flyweight division. Johnson announced his retirement in the state where he last competed, defeating Adriano Moraes by unanimous decision to retain the flyweight championship in May 2023.
“Like I said last time, when I came to Denver, Colorado, I told you guys that was potentially my last fight and I was not lying,” a tearful Johnson said. “I am done competing in mixed martial arts.”
Known for his lightning speed, exceptional wrestling and elusive movement, Johnson’s outstanding MMA career was fought primarily in the UFC and ONE Championship. The AMC Pankration fighter started his UFC tenure as a bantamweight in 2011 and fell short in his attempt to win the UFC 135-pound title against Dominick Cruz . The promotion would introduce the flyweight division in early 2012, which was better suited for Johnson. He participated in a tournament to determine an inaugural flyweight champion and defeated Joseph Benavidez by split decision at UFC 152 to claim gold.
