Watch ONE flyweight champ Demetrious Johnson take on 'big f*cking' BJJ heavyweight

“That’s a big f*cking dude!”

ONE flyweight champion Demetrious Johnson realized he may have bit off more than he could chew as he approached the mats.

Michael Sante Medina, a 6-foot-3, 248-pound BJJ heavyweight champion, stood in position waiting for “Mighty Mouse’s” arrival for the open-weight tournament at the 2024 Pan IBJJF Championships. Johnson, who stands at 5-foot-3, weighed in at 155 pounds for the event.

“If I don’t make it, tell my story to my wife, OK?” Johnson said into the camera on an all-access video on his YouTube channel.

Regardless of the size difference, Johnson took a bow and jogged onto the mat, eager to figure out how to solve a massive puzzle.

It wasn’t easy early on, as Medina swung Johnson around like a small child – or, as Johnson would describe it, like a scene from “Teenage Mutant Ninja Turtles II: Secret of the Ooze” when Rahzar spun Michelangelo in circles before launching him across a warehouse.

Perhaps unsurprisingly as one of the best mixed martial artists to ever do it, Johnson figured out a way to get the job done, and ended up tapping his much larger opponent.
