Jack to do 'whatever it takes' to beat DeGale

Updated: 

Badou Jack warned "don't blink, because this one could be over quickly" and vowed to do whatever it takes to beat James DeGale in New York on Saturday.

WBC champion Jack and IBF belt holder DeGale will put their world titles on the line in a super-middleweight unification showdown at the Barclays Center in Brooklyn this weekend.

The two fighters have both lost just once in their professional careers and Swede Jack is confident he can make light work of beating the 2008 Olympic champion from Great Britain.

"On fight night, none of the talk matters. You have to back it up in the ring. I'm just excited about the fight. I'm not focused on anything else other than that. I just need to win," said Jack.

"I've been paying attention to DeGale for a while. You have to study your opponent a little bit for a fight this big. I'm ready to anything it takes to win the fight.

"I promise the fans it's going to be an exciting fight. Don't blink, because this one could be over quickly. One punch can change the fight.

"This is champion versus champion. It's finally here. I'm going to put on a great show and become the unified champion, no matter what it takes.

"To be at Barclays Center in Brooklyn is amazing. It's a unification fight so it doesn't get any bigger than that. It's boxing and anything can happen, but on fight night I'm going to find a way to get the victory."
