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.
