MMA veteran Tamdan McCrory was sitting close by with camera phone in hand to capture the incident.
The footage starts with Diaz and Johnson jawing face-to-face. Diaz then pushes Johnson and they are quickly separated.
“I’ll smack the sh*t out of you, bitch,” Johnson shouted as he was being restrained. “You got your boys so you wanna act tough?”
That’s a good little teaser for Saturday’s showdown. Friday’s weigh-ins should be interesting, as well.
Amway Center in Orlando, Florida hosts the festivities.
