Frank Mir is not someone to take lightly, and things can escalate quickly when ego enters the equation — as it often did with Jason "Mayhem" Miller.
The two were teammates for years, with Mir becoming a UFC heavyweight champion and Miller experiencing a mix of success and struggles both inside and outside the Octagon. Known for his antics, "Mayhem" often tested the limits with his teammates in training — a habit Mir experienced firsthand.
During one infamous training session, things reached a boiling point, nearly resulting in a serious injury to Miller. Mir shared the story during an appearance on the JAXXON podcast.
We were training at Marc Laimon’s gym, and Laimon said, ‘Hey, Frank, practice is over ... once you finish somebody.’ So I just turned it on and started tapping everybody,” Mir recounted. “Then I got to Mayhem, and I put him in a guillotine, and he almost killed himself. He ran his feet up the f***ing cage, trying to flip over me — it was weird. So I let it go, and then I caught him in a kimura.
I started cranking it and thought, ‘I’m not letting go. F*** this. Today you’re going to learn!’ So I put his hand to the back of his head.
