Zion Clark, All-American Wrestler Born W/O Legs, Is Taking MMA Fight

"It's the same as it was wrestling for me. I just wrestle against able-bodied people, and I beat able-bodied people. Now I'm fighting able-bodied people, and I'm gonna knock out able-bodied people. It's as simple as that. I'm a fighter."

Zion Clark is once again proving there's absolutely NOTHING he can't do -- despite being born without legs -- the former All-American wrestler tells us his next crazy accomplishment ... is taking an MMA fight!

"I'm trying to run this s**t up! It's not just a rinky-dink fight. This s**t's going on pay-per-view. This shit is a legit sanctioned fight," Zion told Babcock and Mojo on the "TMZ Sports" TV show (airs weekdays on FS1), adding, "It's gonna be big!"

There's a good chance you've seen or heard about the 25-year-old's incredible story.

Clark was born in Ohio in 1997 with a rare birth defect called Cadual Regression Syndrome which caused him to be born without legs. Zion was put up for adoption after he was born. He bounced around the foster care system.

In elementary school Clark was introduced to wrestling ... but he wasn't very good at first. In fact, he didn't win a single match for years. But, after meeting his H.S. wrestling coach, Zion and the man developed a bond, and ZC's wrestling ability improved dramatically.

As a senior, he finished 33-15 ... wrestling against kids who had four limbs. Clark then went to Kent State, where he continued his successful wrestling career.

Zion's now training for the 2024 Olympics ... where he'd like to wrestle. He's also gunning to compete in the Paralympics in wheelchair racing ... where he's one of the most elite racers in the world.

He's also known as the "fastest man on two hands" ... Zion was a track champ in high school, too.

Clark also recently set two Guinness World Records ... for highest box jump (record was 24 inches. Zion jumped 33) with the hands and most diamond push-ups (248 in under 3 minutes).

As for Clark's MMA fight ... it's scheduled to go down December 17. Zion says he doesn't even know his opponent's name ... that's how unbothered he is about the fight.

It's not that he isn't taking the fight seriously ... in fact, it's just the opposite. Zion says he's beating his ass in the training room, sparring with MMA stars like Rampage Jackson and AJ McKee.

Check out the clip ... Zion talks about training with those legends, and what we can expect when he steps in the cage for the first time in just a few weeks.
