Dierry Jean launched an extraordinary barb at the unbeaten pound for pound contender Terence Crawford as the final press conference, telling him he was going to "beat [his] ass".

The Haitian-born Canadian challenger looked in high spirits as he addressed the assembled media in Omaha, Nebraska, Crawford's hometown ahead of his WBO World Super-Lightweight title challenge tonight at 1am UK time.

He stood on the podium and let go a shot at Crawford after a previously quiet and respectful build-up.

"Thanks for the team Crawford. And I promise you on Saturday, not being disrespectful, I'm gonna beat your ass man!" Jean claimed as Crawford smiled and laughed, before replying.

"You gotta quit listening to those people, man. They're pumping your head up!"

"I'm going to put on a great show. I know Jean's in shape. I know he's hungry. But I don't think he's more hungrier than what I am right now."

The two men then shared a fiery face off before what promises to be an entertaining fight EXCLUSIVELY LIVE in the UK on BoxNation tonight from 1am. Subscribe to BoxNation NOW to watch this one!
