Holloway was expected to win the fight via judges’ decision before he knocked out Gaethje. He picked up his 26th win of his MMA career.

"This is the moment," Holloway added. "This is what the BMF is known for. If that’s not a BMF moment, I don’t know what is. If Justin was up, he would’ve given me those ten seconds."
