WATCH: Mikey Musumeci tears opponent’s leg into pieces with gnarly leg lock

Reigning and undisputed ONE flyweight submission grappling world champion 'Darth Rigatoni' Mikey Musumeci of the United States is getting ready to return to action when he faces fellow American Kade Ruotolo for the ONE lightweight submission grappling world title.

Musumeci and Ruotolo are set to lock horns at ONE 168: Denver, in ONE Championship's highly anticipated return to U.S. soil.

The event broadcasts live from the Ball Arena in Denver, Colorado.

Before the action goes down in front of millions of American fans, it's a great time to check out an instant Mikey Musumeci classic, as a reminder of just how dangerous 'Darth Rigatoni' is on the mats.

ONE Championship posted this YouTube video highlight of Musumeci's January 2023 victory over Mongolia's Gantumur Bayanduuren.

In this matchup, 'Darth Rigatoni' caught his opponent with his signature leg lock, and proceeded to wrench the limb into an alligator roll. With Bayanduuren refusing to tap, Musumeci cranked even harder, tearing his opponent's leg and ligaments.

The Italian-American superstar would end up winning via unanimous decision, but the damage had been done.

Will he be able to do the same to Kade Ruotolo? Find out soon.

Fans in the United States and Canada can catch all the action of ONE 168 live and absolutely free on Amazon Prime Video. It airs Friday night, September 6th, beginning at 8:00pm ET.

Mikey Musumeci getting ready to move up three weight classes for Kade Ruotolo showdown: "I just train every second"

'Darth Rigatoni' Mikey Musumeci is coming all the way from flyweight to challenge the lightweight king Kade Ruotolo, which is a full three weight classes above where he's used to. This is a commendable feat in and of itself.

In a recent guest appearance on The MMA Hour, Musumeci talked about how he has been dealing with the move to a higher weight class.

'Darth Rigatoni' said:

"I just train every second. Ever since I'm four years old, [for] 23 years I've been training like every second. I was running six miles a day for a while, but now I have to be heavier so I can't run as much because it makes me too skinny."
