Demetrious Johnson checked in with the Extra Rounds Podcast before he defends the UFC flyweight title against Henry Cejudo at UFC 227.

Demetrious Johnson will look to extend his incredible UFC title defense streak to an even dozen when he defends his flyweight title against Henry Cejudo this Saturday night at UFC 227.

The event will take place at the Staples Center in Los Angeles, California and the bout will be featured as the co-main event and the first of two title fights. This will be a rematch — something Johnson has been accustomed to being a part of as the only champion in the division’s history — from UFC 197, in which “DJ” finished Cejudo in the opening round.

While many believed Cejudo was a little too green for his first title opportunity, “The Messenger” has been taking a much different approach to his second shot at the flyweight title. If you follow Cejudo on Instagram, you may have seen mention of this approach — mixing fighting with science.

Johnson hasn’t been following along his opponent’s journey on social media, but he is excited to see Cejudo’s preparation come to light in Los Angeles.

“Athletes train and you can travel around the world, which I’m sure he’s traveled around the world before for other fights and it seemed to help him out,” Johnson said while appearing on the Extra Rounds Podcast. “I’m looking forward to testing science and seeing how science holds up against old-fashioned grind it out in the gym.”

After losing to Johnson in their first encounter in April 2016, Cejudo would lose a controversial decision to Joseph Benavidez, eight months later, at the TUF 24 Finale. Since then, the 2008 Olympic gold medalist has picked up back-to-back wins over Wilson Reis and Sergio Pettis. As much as Cejudo has evolved since their first fight over two years ago, Johnson has evolved as well.

“Yeah (I’ve been impressed),” Johnson said. “He knocked out Wilson Reis, fought Sergio Pettis — who is a young stud — beat both of those guys. I’m always looking forward to a rematch. We go in there, mix it up a little bit and see what’s improved and what’s not. Also, we can see how much I’ve improved too. We’ve definitely both evolved. He’s a young guy, very scrappy, very gritty in the scrambles, good hands. He’s an interesting fighter. With me, I wasn’t just sitting on my butt. I have been trying to stay healthy, keep up with the younger division and that’s how I’m staying focused.”

“I’m looking forward to testing science and seeing how science holds up against old-fashioned grind it out in the gym.”

Since UFC 197, the soon to be 32-year-old Johnson has defeated Tim Elliott via unanimous decision and had submission victories over Reis and, most recently, Ray Borg in one of the most memorable finishes in UFC history. With 30 fights in his professional career, there isn’t much that “Mighty” hasn’t seen in the cage.

“I’m prepared for everything in this sport,” Johnson said. “I fought the best Japanese fighter, Kyoji Horiguchi, he’s cleaning house in Japan right now. I fought the man he lost to — Joseph Benavidez — I’ve been actively fighting tough opponents, going through five-round fights and handling my opponents. I’m sure he’s going to come out and be more timid, take his time and try to ease into it. He won’t have the opportunity when he fights me. I go from the first bell to the last.”

The booking of both title fights at UFC 227 came as somewhat of a surprise considering Johnson and bantamweight champion TJ Dillashaw, who will defend his title against Cody Garbrandt in the main event, was seemingly on a collision course. The fight never materialized.

Does matching both champions on the same card have any significance?

“We’re going to find out,” Johnson said. “I’ve got a lot on my plate right now. My wife’s pregnant so after this fight, I’ve got to come home and get ready for her to give birth. Both of my kids are starting school. There’s a lot more on my plate than figuring out who my next opponent is. Right now I’m just focusing on Henry Cejudo. After this fight, I’ll sit down with my management, my coaches and see where it goes from there. At the end of the day this is a business. Everyone keeps talking about super fights and when you think about those super fights, it’s got to be one that’s worth it.”

In recent interviews Cejudo, along with his manager Ali Abdelaziz, have said, essentially, that the “best thing that could happen” for the UFC flyweight division would be for Johnson’s history-making title defense streak to come to an abrupt end this Saturday night. To say Johnson would disagree with their sentiment would be a vast understatement.

“They’re f****n high,” Johnson stated.
