Cody Garbrandt Down To Fight Brandon Moreno, Promises KO Or Submission

Cody Garbrandt is ALL IN on a fight with Brandon Moreno … telling TMZ Sports he wants a tilt with the champ, and he’s promising a knockout or a submission when it happens!!

“No Love” broke it all down for us outside the Roosevelt Hotel on Friday … saying he’s been eyeing a move from bantamweight to flyweight for a while.

And, he tells us a fight with Moreno — who just called Cody out this week — is the perfect opportunity to finally make that happen.

“I’ll finally get to fight at my natural weight [of 125 pounds] where I think I can perform my best,” says Garbrandt, who tells us he’s already started the process of changing around his diet and workout routine.

“I feel like I’m a way better fighter than him.”

Don’t get it twisted, though … Garbrandt respects the hell out of Moreno — telling us he believes the dude is a legit champion.

But, if the fight does get made … Cody says he sees it all ending with him on top via some kind of finish.

“I’ll finish him for sure,” Garbrandt says. “KO, submission. Whatever.”
