Here is what the fighters had to say Wednesday:

JERMALL CHARLO

"I know that Jorge is a come forward kind of fighter. He's going to try to put a lot of pressure on me. It's my debut at 160 pounds so I get a chance to go up against someone who's never been knocked out before and who has knocked out known fighters. I'm preparing for the best of him.

"I want to continue to move up to the bigger names, like I've been doing. Hopefully my performance in this fight will get me more notice from those big names and get me those fights.

"This is a new Jermall Charlo who's better, bigger, faster and stronger. It's my job to show everyone that on Saturday night.

"There are a lot of big fights at 160 pounds for me. I paid my dues at 154 pounds. I stuck around there so that I could climb up the ranks. The timing is perfect.

"My job is to go in there and do what I know how to do. Hopefully I can corner one of those big names soon. I'm not running from anyone. I'm here to fight the best in the world.

"The weight naturally comes off during camp, but now that I don't have to stress as much for it, it feels like the way it always should have been.

"Me and my brother both have been through adversity and our time is now. I want to be one of the best fighters in the world and my job is to take care of this step right here.

"I love being here in New York. This is one of those dreams come true moments. I've always wanted to fight in New York."

JORGE SEBASTIAN HEILAND

"I am so thankful for this opportunity to be on such a big card. I'm really happy with how welcoming everyone in New York has been. I couldn't be happier or more focused on this fight. This is a crucial fight for me and I can't wait until Saturday.

"The key for Jermall will be his speed. He's a fast boxer but he's jumping up a division. I've been at this weight almost my whole career. I know he will be prepared, so I have to be too. Without a doubt, it will be a battle.

"I've tried different methods of training to improve my punching power and I think it's worked. The training has given me more strength and power in my punches."
