The fight has been sanctioned as a WBC heavyweight eliminator.

Both boxers are coming off tough bouts.

Earlier this year, Ortiz had to overcome two knockdowns to score a dramatic knockout of former world champion Charles Martin.

Last year, Ruiz too had to get off the floor to win a twelve round unanimous decision over Chris Arreola.

Ortiz will be looking to put Ruiz down for the count.

“I feel so good both physically and mentally. I’m eagerly awaiting this fight and you’re not going to want to miss it when we get in that ring," Ortiz said. “After I fought Charles Martin, I was back in the gym a week later. Whether I have a fight or not, I’m always active and staying ready.

"My intention is to knock out Andy Ruiz. One of us is getting knocked out and I can guarantee this one doesn’t go to the judges. I have studied Andy from top to bottom. If I don’t knock you out with one punch, then I’m just going to chip away at you until you can’t go anymore.

“I’m just focused on myself and doing my job. What’s going to cause Ruiz trouble in there is me, regardless of what kind of style I’m using. I’m always trying to reach the top of the mountain. I want the top prize. This is a very important fight for me, but so is every fight. They all get me closer to another world title shot. It’s all about training, training and more training. I feel better now than I did when I was 25.”
