Mikey Musumeci Is Defending His UFC BJJ Title After Training With Umar and Ditching the Leg Locks. He's Never Been More Interesting.

The man they called a butt scooter is about to defend a UFC title.

Mikey Musumeci — five-time IBJJF world champion, the best pure jiu-jitsu player at 125 pounds, and the human being specifically targeted by the UFC BJJ no-butt-scooting rule that the promotion quietly abandoned once they realized they needed him — is putting his bantamweight title on the line at UFC BJJ 9 on June 4.

And he showed up to this camp different.

Somewhere between the last defense and this one, Musumeci ended up on the mats with Umar Nurmagomedov. Not for a fun photo op. Training. The internet produced the evidence, named him 'Dagestani Mikey,' and waited for him to deny it. He did not deny it. He leaned into it.

He also told reporters the leg lock game is benched for this fight. Strategically, not permanently — but he's walking into a title defense without his most reliable finishing system. Why? His own quote explains it better than anything I can write: 'I've just been called a butt scooter and like a wimp so long that I just want to go out there and just scrap.'

This is the five-time world champion. The man who submits elite grapplers while sitting on the floor. He's tired of the label, so he's training Dagestani wrestling and shelving heel hooks for a title fight. That's not an identity crisis — that's a guy with a point to prove.

There's a bigger thread here. Musumeci has been publicly critical of IBJJF scoring for punishing attacking jiu-jitsu. His quote with training partner Jackson Nagai: 'Attacking doesn't favor you. It's so easy to lose in the IBJJF ruleset because of how many variables there are.' He said this two weeks before a title fight in a promotion whose entire pitch is submission only, finish or lose. He's not being inconsistent. He's telling you where he thinks jiu-jitsu should live.

UFC BJJ has 14 events planned for 2026. They need a champion who's a story, not just a scoreboard. Musumeci is the only athlete on their roster who was already famous before they launched. His title defenses are proof-of-concept arguments for whether submission grappling can build a real sport calendar — with actual divisions, actual stakes, actual characters.

His opponent on June 4 hasn't been confirmed at press time, but the card also features Nicky Rodriguez defending against Roosevelt Sousa — a man serving a three-year IBJJF ban for meldonium that UFC BJJ has decided is not their problem.

So: the promotion that banned butt scooting is built around a butt scooter. The submission-only format is championed by a man who's scrapping the submissions for this camp. The event features one USADA-banned challenger the organization is choosing to ignore.

UFC BJJ is interesting in spite of itself. Mikey Musumeci is the reason why.
