Keith Thurman plans to knock out Shawn Porter in welterweight showdown

Keith Thurman has promised to live up to his "One Time" nickname when he defends his WBA welterweight title against Shawn Porter later this month.

The 27-year-old will put his 27-fight unbeaten record on the line at the Barclays Center in New York on Saturday June 25, live on Sky Sports.

His fellow American Porter, 28, is a former IBF welterweight champion who lost the title to Britain's Kell Brook in his only defeat in August 2014, but Thurman plans to knock him out.

Thurman, who has won 22 of his fights inside the distance, said: "I'm ready for Shawn Porter. We're going to box harder, box stronger and box better. I will be the better man.

"Training is the fundamentals of getting one prepared. We've always known that Shawn Porter was going to come into this fight in tremendous shape. That's what his training methods are all about. But the Energizer Bunny has never been hit by Keith Thurman, and I'm pretty sure I could stop it in its tracks.

"I'm going for the knockout. I've stated it before. My hands are itching for a knockout. I'm 'One Time,' all the time. That's my philosophy. Every single time I step into the ring I'm looking for the knockout. We don't get paid for overtime.

"I've always considered myself a knockout artist. Back to when I was a teenager knocking out grown men in headgear. Ever since then, I've been dropping people like a bad habit.

My hands are itching for a knockout. I'm 'One Time,' all the time.

"I love being a power-puncher. My favourite fighter of all time is Mike Tyson. One of my goals that I set when I was a kid was to have more knockouts than Mike Tyson throughout my career.

"This is an opportunity to showcase our talents and our skills to the world. The winner will have an opportunity to be the head guy in the sport. I've always wanted to have a legacy in the sport of boxing."

The fight was originally scheduled for March but was put back to June after Thurman was injured in a car accident in February.

His trainer Dan Birmingham has revealed Thurman has put the delay behind him and is now working on his plans to overcome Porter.

He said: "Life happens. Keith was involved in the accident and so we took the necessary rest. He saw the right doctors and we're back now. We're ready for Shawn Porter.

"We're constantly conditioning. We're working on attacking his style. He's a short, come-forward brawler who's going to try to come into Keith's chest and make it a war. We're making our adjustments.

"Keith has to be busier, more in charge fighter. He has to work off of his jab and then his power will keep Porter at bay."
