Kell Brook will make his fourth IBF Welterweight World Title defense against U.S. star Errol Spence Jr. at Bramall Lane in Sheffield, England this Saturday May 27, live on SHOWTIME (5:15 p.m. ET/2:15 p.m. PT).

Brook (36-1, 25 KOs) and mandatory challenger Spence, (21-0, 18 KOs), clash on SHOWTIME CHAMPIONSHIP BOXING in one of the biggest fights in the 147-pound division, and the elite pairing are promising to deliver an electric night of action.

Both fighters participated in a public media workout today, Wednesday, at Peace Gardens in Sheffield, England. Below is what Brook had to say:

KELL BROOK - “We are going to rock Sheffield on Saturday night. I’m ready, I’m pumped, I can’t wait.

“There is a lot of pressure but I always perform better under pressure. I’m meant to be on the big stage, I’m ready for the pressure and to see the bright lights.

 "[Errol Spence] is a serious dude from America, he’s a young hungry lion, but he’s not beaten anyone like me. I’m a champion and I’ve been a champion. I’m defending. I know both sides of the coin, I’ve prepared very well.

“I’m ready for a war. And that’s what you’re going to see – a war Saturday night. There are going to be two winners Saturday night: that is going to be myself and everyone watching.

“There’s no way he can beat me.  I’m a man possessed and I have a serious job to do.  This is my night to shine.

“I love it [being the underdog].  I was born for it.  People don’t have me winning this fight, but that just gives me the extra energy I need to go out and prove them all wrong.

“This guy is a talented guy, but he’s never been tested.  He’s never been in with someone who is so determined like me.  Who’s bigger, stronger, who has all this energy, who’s meant for this game, who’s meant to be a winner.  He hasn’t been in with someone with that mindset, and that’s what I’m coming to bring on Saturday.
