IBF welterweight champion Errol Spence expects a very tough challenge when he makes his first world title defense against Lamont Peterson on January 20th at the Barclays Center in Brooklyn, New York.

Back in May, Spence (22-0, 19 KOs) traveled to England to dethrone Kell Brook for the IBF title before a rabid crowd in Sheffield.

In the fight against Brook, the bout changed in the second half when Spence took over the contest and broke the Sheffield fighter down for a stoppage victory in the eleventh round.

Some have questioned the heart of Brook, as he went down to a knee for the full count after suffering a fractured orbital bone during the action. It was Brook's second fight in a row where he was stopped after suffering a fracture orbital bone.

While some view Peterson as a heavy underdog, Spence views him as being a better fighter than Brook - and also possessing more heart. And Spence anticipates a much tougher outing.

"You're going to see the same Errol Spence that you're used to," said Spence. "I can't look ahead because I know how dangerous Lamont Peterson is. I've been in training camps with him and I know what he can do.

"I've seen too many fighters look down the road and get beat before they get to the big fight. I have to be 100 percent focused and hungry. I'm fully dedicated to this fight. Lamont can push me to even greater levels. I feel like he is a better fighter than Kell Brook and has even more heart than Kell Brook and he can bring out the best in me.

"I think it's going to start out as a boxing match, but as we go on, it's going to be a dogfight. We both have big hearts. I've never known Lamont to turn down any fight. Not a lot of people wanted to fight me."
