ONE Lightweight Submission Grappling World Champion Kade Ruotolo and Japanese juggernaut Hiroyuki Tetsuka are preparing for one of the most fascinating stylistic clashes on The Inner Circle.
The pair will collide in a high-stakes lightweight MMA showdown this Friday, May 15, at Bangkok’s Lumpinee Stadium, with the blockbuster event airing live exclusively for subscribers on live.onefc.com.
For Ruotolo, the highly anticipated matchup marks his return after more than a year away from competition due to a devastating knee injury.

For Tetsuka, it represents a golden opportunity to prove he belongs among the lightweight division’s absolute elite while moving one step closer to a World Title shot.
Ruotolo Returns After Brutal ACL Tear
Kade Ruotolo looked completely unstoppable in his most recent MMA appearance.
At ONE 171: Qatar in February 2025, the American phenom submitted Nicolas Vigna in the first round to improve to 3-0 in mixed martial arts and continue his rapid rise inside the all-encompassing sport. But only days later, momentum suddenly turned into disaster.
During a routine training session, Ruotolo suffered a freak injury that forced him into the longest layoff of his entire career.

He told onefc.com:
“I ended up just doing like a really weird tweak in my knee off of a takedown scramble, and I just heard a huge pop in my knee, boom, and I knew it was serious. And then it ended up being the ACL full tear.”
The catastrophic injury sidelined the lightweight star for more than a year and forced him through grueling months of rehabilitation.
At one point, Ruotolo admitted he had to relearn how to walk normally again. Mentally, the recovery process proved just as difficult. Watching his twin brother, Tye, continue competing — including his impressive victory over Adrian “The Phenom” Lee — helped keep him deeply motivated while he slowly rebuilt his body through rigorous physical therapy and recovery work.
Now completely healthy once again, the 23-year-old phenom steps directly back into one of the toughest tests of his MMA career.

Ruotolo sees the “Japanese Beast” as a physically dangerous and surprisingly complete mixed martial artist whose toughness and composure make him far more than a one-dimensional striker.
The American said:
“I think it’s pretty obvious he’s got a very strong frame, so he’s an explosive and strong fighter. He’s got some density in his punches it looks like, like hitting the body and the head as well with that overhand. So, also throws a good high kick as well, so he’s pretty well-rounded in the striking department.
“Shinya Aoki was able to get him down, but he stayed calm and found the exit, right? Shinya is arguably one of the best jiu-jitsu guys to do it in MMA, right? So he’s got striking, he’s got some grappling, it’s gonna be a tough scrap guaranteed.”
Tetsuka earned widespread attention last November when he stopped legendary former ONE Lightweight MMA World Champion Aoki in the second round at ONE 173 after moving down from welterweight.
That spectacular performance reinforced the Japanese veteran’s reputation as one of the division’s most dangerous finishers. Ruotolo, however, firmly believes his own evolution as an MMA fighter has accelerated rapidly during his lengthy recovery period.

Ruotolo offered:
“I do believe that my tools have been coming along, just growing in a big way and the same for my brother, so I think our striking is getting a lot better.
“I wouldn’t be surprised at all in the midst of me trying to take him down and get him to the ground, I land a big shot, big head kick or whatever like that.”
Tetsuka Believes His Experience Will Be The Difference
While Kade Ruotolo enters the Circle carrying massive global hype and elite grappling credentials, Hiroyuki Tetsuka believes his vast experience and complete MMA ability will ultimately tilt the fight in his favor.
The “Japanese Beast” has spent more than a decade grinding through high-level competition, building a fearsome reputation through raw aggression, absolute toughness, and devastating knockout power in the world’s largest martial arts organization.
So, when he received the call to face one of the world’s most celebrated submission grapplers, his reaction was sheer excitement rather than hesitation.

The 36-year-old said:
“Honestly, I was just happy. He’s a globally recognized name, and his grappling is genuinely world number one level.
“Being able to fight someone with that kind of name and reputation, I’m really proud of that. And I’ve watched his technique a lot, so being able to experience it firsthand, to test myself against it, I’m genuinely excited about that.”
The Japanese veteran fully understands the immense danger waiting for him if the ONE lightweight submission grappling king secures dominant positions on the canvas.
Still, after over a decade of professional experience, Tetsuka remains fiercely convinced he can survive those perilous moments and drag the American into highly uncomfortable territory.
He said:
“I’ve had 21 professional fights and I’ve never been submitted once.
“There have been high-level grapplers in there too, and I’m confident I can defend it, and I’m confident I can beat him. That said, I fully expect the finishing power he has to be something I’ve never felt before.”
Tetsuka also firmly believes his years of experience across all aspects of MMA give him a major advantage over Ruotolo, who remains relatively early in his mixed martial arts journey despite his world-class grappling pedigree.

Now riding massive momentum from his statement win over Aoki, Tetsuka sees this matchup as the ultimate breakthrough opportunity that would push him directly into the ONE Lightweight MMA World Title conversation.
The “Japanese Beast” concluded:
“If I beat Ruotolo, I think I should just get it next.
“I’ve got about eight wins at this point. If I win this one, it’s time for ONE to give me a title shot and a bonus.”
