Agyarko (18-0, 7 KOs) will challenge Kelly (18-1-1, 9 KOs) on the undercard on Anthony Joshua’s heavyweight fight with Kristian Prenga on DAZN pay-per-view.

When he was a 20-year-old amateur, Agyarko was on a night out in Belfast city center when he was attacked by a group and stabbed.

The knife cut down Agyarko’s face and neck but miraculously missed any vital areas. He recovered, turned professional a year later and began a slow climb to world title level.

Now 29, Agyarko is talented but has flitted between promotional companies and endured spells out of the spotlight. Nonetheless, he has remained unbeaten and navigated his way through the world rankings.

In April, he finally thought his big moment had arrived, but he saw a final eliminator for Kelly’s belt fall apart when his opponent, Brandon Adams, collapsed before the weigh in.

A crushing disappointment at the time, Adams' withdrawal eventually led to Agyarko getting this shot at Kelly.

“It's been a a tough journey to to get here, and I believe God's always been on my side,” Agyarko said at Thursday’s final press conference.

“I’ve faced some very mentally challenging situations in my life. To be here right now, it just shows how mentally resilient I am, and I just believe I have that edge.

“I'm prepared for the best Josh Kelly, and I can't wait for Saturday night.”

In January, Kelly finally fulfilled his own undoubted potential when he outpointed Bakhram Murtazaliev to win the 154-pound title.

The win seems to have done wonders for the 32-year-old’s confidence and he has talked about grasping control from the first bell and making Agyarko quickly doubt himself.

Agyarko has long spoken about his determination to create history and become the first Black Irish world champion. His chance has arrived, and he's in no mood to let it pass by without a real fight.

"He's going to be confident. He's world champion and he's obviously a good fighter, but this nonsense that I’m going to lose confidence early on? I’ve heard it all before by previous fighters and I'm still unbeaten. I'm still here.

“But it's my time to go out and prove everybody wrong, just like I have for the last three, four fights. I've been the underdog, the B-side in the last three four fights and I've always come out on top.

“I'm prepared for the best Josh Kelly and you're going to see the best Caoimhin Agyarko on the night, and no doubt it's going to be a great fight.

“I believe that I'll create history on Saturday night. I will run through brick walls to become the first Black Irish world champion. and if I have to beat the best Josh Kelly then so be it.”
