He jumped in to stop a fight at an early UFC event and broke the winner's nose in the process.
I had never heard that before. It made me go search around the Internet to find out what happened. I found this interview someone did with BJM and it was the fight between Brian Johnston and Reza Nasri and John actually didn't break his nose but hit him pretty good...heh.
And so as not to pull a KenFlo the original interview was from
www.thegarv.com
Interviewer: Then you started reffing and at UFC 11, Brian Johnston. When you broke up the fight it appears as though you broke his nose in the process. Is that correct?
BJM: No, it's not correct. But it's a good story, everyone goes with it.
Interviewer: I remember that fight and it looked like you hit him a good shot to the nose.
BJM: I did. I did hit him. My forearm hit his nose. What happened was Brian was fighting a guy named Reza Nasri, who was a wrestler from Iran. They had some bad blood before it and Reza was saying he was going to do certain things to Brian. And during the fight, Brian actually, he hurt Reza Nasri right away as Reza was trying to come in on him. And when I stopped the fight it was because Brian Johnston had actually broken Reza's nose and driven it as far over as I had ever seen anyone with a broken nose, drove his nose over in towards his right eye. And that's where I went in to get Brian off him and my forearm came up as I was trying to lift Brian up to push him out of there. And it did hit Brian's nose. It didn't break it, but it did draw some blood from it. And it was funny because the first thing he did was damn John you hit my nose. You can see that. But then he started yelling at Reza Nasri, you know, saying what now and some other expletives and stuff, but everyone looked at it like he was yelling at me.
