TMZ Sports ran into the 38-year-old (retired, for now, at least) former UFC champion at LAX on Friday … and asked him about the Problem Child’s foray into MMA.
“Stop trying to fight little dudes. F***ing  pounders. You’re a middleweight. If you want to fight a middleweight, I got hands. We can do anything we want. I really don’t care. I’d beat that guy in my sleep.”
As we previously reported, 26-year-old Paul recently signed a multi-fight, multi-year deal with PFL … and wasted no time by calling out Nate Diaz for a boxing and MMA fight.
Diaz hasn’t yet accepted the challenge … and if he doesn’t, Rockhold is more than ready to step in.
“I got some freedom to do some things and as you can see, I like throwing hands these days,” Luke said, adding, “fight people your own f***ing weight. Straight up. And champions, a real champion, a real contender. A real someone who can put you on your ass. not old guys, 55-year-olds, or lightweights. You can’t even get above a welterweight, dog, So, step up.”
