Kade Ruotolo Returns From ACL Tear to Face Hiroyuki Tetsuka at The Inner Circle on May 15

The 23-year-old California native makes his fourth MMA appearance against former Pancrase Champion Hiroyuki Tetsuka in a lightweight fight at The Inner Circle on Friday, May 15. The show broadcasts live exclusively via live.onefc.com.

Ruotolo has been one of the most exciting stories in combat sports since transitioning to MMA in June 2024. He submitted Blake Cooper, Ahmed Mujtaba, and Nicolas Vigna all in the first round across nine months, but a serious injury after his last fight put his momentum on hold.

He is now fit and ready to resume a run that has the division buzzing about a potential title shot against reigning ONE Lightweight and Welterweight MMA World Champion Christian Lee.

Kade Ruotolo Opens Up on ACL Tear That Kept Him Out of Action

Ruotolo's return to The Inner Circle carries extra significance after the injury he sustained following his win over Vigna. The American grappling star did not hold back on the severity of what he went through.

"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," Ruotolo said.

A full ACL tear is one of the most terrifying injuries any athlete can navigate. Ruotolo's 29-3 BJJ record, three submission grappling title defenses, and three first-round MMA submissions make him the most dangerous grappler Tetsuka has ever faced, regardless of the Japanese fighter's impressive submission defense reputation.

Tetsuka Confident He Can Defend Submissions on May 15

Tetsuka, a former Pancrase Champion, has never been submitted in 21 professional MMA fights, and the Japanese veteran is drawing on that record as a source of confidence heading into the toughest grappling test of his career. His respect for Ruotolo, however, is genuine.

"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 explained.

Tetsuka is a 36-year-old veteran with a 15-6 professional MMA record and seven ONE victories, six via finish. He arrives off a career-defining second-round TKO of former ONE Lightweight MMA World Champion Shinya Aoki at ONE 173 last November, the biggest win of his promotional tenure.

Ruotolo Breaks Down Tetsuka and Predicts a Tough Fight

Ruotolo has done his homework on the Japanese veteran and arrived at an assessment that gives Tetsuka genuine credit across multiple dimensions of the sport. The way the American described the "Japanese Beast’s” escape from Shinya Aoki tells the full story of the challenge in front of him on May 15.

"I think it's pretty obvious he's got a very strong frame, so he's an explosive and strong fighter. 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," he said.

Ruotolo himself defeated Aoki on his ONE submission grappling debut in 2022, giving this matchup an interesting thread connecting both fighters to the same legendary Japanese grappler. Whether Ruotolo can do what Aoki could not and submit Tetsuka is the defining question of May 15.
