After numerous postponements, George Kambosos is finally a few days away from his scheduled showdown with unified lightweight champion Teofimo Lopez.

The bout was postponed several times, due to Lopez contracting COVID and then Triller, who had the promotional rights, were unable to stage the event.

Eventually Eddie Hearn's Matchroom were able to secure the promotional rights and will stage the card on November 27 at the Hulu Theater in New York's Madison Square Garden.

Kambosos (19-0, 10 KOs) is a huge underdog in the fight, with Lopez taking part in his first fight since beating Vasiliy Lomachenko last year to unify the WBO, IBF, WBC Franchise, WBA lightweight belts.

Lopez is predicting a knockout win in the early rounds - a prediction that Kambosos shoots down.

"My speed and the way I move and explosive power and shots that I land and throw and the punches in bunches and the combination punches that I have in my artillery, and my stamina and my fitness is just too much for this kid. He's been saying he'll knock me out first round. Before he got COVID on June 19, he said he was going to knock me out within three, so what's changed?," Kambosos said to AAP.

"His fitness and his stamina is nowhere near what it has to be so he's hoping and he's praying that it's one round because it has to be. What's he going to do for the next 11 when he doesn't get that first-round knockout? If that's his only game plan, then he's in big, big trouble. I'm fully prepared. I'm ready for 12 rounds. I'm old school so, if they want, we can do 15 rounds like the greats of our sport.

"I've got a big motor. Throughout the 12 rounds, I keep going. Every round I keep getting better and better and keep throwing more punches. But my defense is so underrated in the boxing world. I'm super sharp and my reflexes, my head movement, my footwork in and out, they're going to find out the hard way - Lopez is. They don't believe in my defense and think this is going to be an easy fight for him, but they're going to find out the hard way."
