Heavyweight contender Jarrell Miller declared "it's about time I knocked out a Brit" after maintaining his unbeaten record with a demolition of Bogdan Dinu.

Miller brutally stopped Romanian Dinu - who had won all 18 of his previous fights - in the fourth round of their heavyweight meeting at the Kansas Star Arena on Saturday.

The American slugger is now looking over the Atlantic for his next opponent, with Dillian Whyte or Dereck Chisora in his sights.

"We're just trying to work out what to do next," the 30-year-old, nicknamed 'Big Baby', stated in the aftermath of his win.

"We want AJ [Anthony Joshua] but he's a little busy, if Dillian Whyte gets past Derek Chisora, I want one of them.

"But I heard about Trevor Bryan, another unbeaten fighter, so I can knockout unbeaten fighters. Let's see if Trevor Bryan picks up his phone, I will kick his behind out as well.

"It's about time I knocked out a Brit. The Brits, right now, are top of the list and there's just me and Deontay [Wilder] as the two undefeated American guys and Deontay's fighting a Brit.

"He's called out AJ but Tyson Fury's stepped up, so if I can't get AJ, I'd like to take Dillian Whyte, Dereck Chisora, even a David Allen or David Price.

"If Eddie Hearn wants it and he comes up with a game plan that I like, let's make it happen."

Miller (23-0-1, 20 KOs) had some trouble in the early going of the fight, as Dinu was moving and countering.

But by the fourth round, Miller had cut the distance - dropping Dinu twice for the knockout win.

“My jab was better than his, but I couldn’t get off my front foot. I’ve been battling a cold since I got to Wichita I knew I was going to get him. That’s boxing, I just needed to adjust. He was getting winded once I started throwing body shots. I had to get my footing down, I knew I would get him," Miller said.

“I come to fight, and nothing was given to me. Putting all the BS aside, I’ve been on my own since I was 17. I’m a fighter and people think I’m 315 pounds and talk smack. I’m a lovable guy and eat cheeseburgers.”
