Browne released a video via social media questioning the credentials of the American – also unbeaten with a 34-0-0-KO33 record – who was last in action when stopping Eric Molina in his first title defence in his home state of Alabama on June 13.
Browne (22-0-0-KO19) said: “I want to talk about Mr Deontay Wilder. The guy’s a WBC champ – well done, congratulations, you’ve got a well-padded record and your promotional team have done really well.
“You’ve got some power, don’t get me wrong. You’re a tall and skinny b****** with chicken legs. That’s unreal. You’ve got some power but your chin is nothing whatsoever.
“I’m a puncher. I’m not saying I’m the best boxer in the world by any rate. I understand this. I know what I am and I don’t try to sugar coat it for the rest of the world. I hit like a mule and I know for a fact that if I hit you on the chin, you’re going to sleep.
“I’ve got a good chin and I can take your shots all day. Your left hook, your straight right. That’s all you’ve got – over and over again. I’ll take it. Then I’ll punish the body, then I’ll take your head off your shoulders.
“Let’s do it. The boy from Australia who wants to make his mark on the world. Of course I want the opportunity and of course I want the pay day. What idiot wouldn’t want those two things?
“I’m 36 years old. I know I can knock you out. Let’s see if you’ve got the balls to bring it.”
Wilder’s retort – also on social media – was short and sweet.
The 29-year-old said: “I would respond if I could understand you…”
Browne, who is managed by Ricky Hatton, is hopeful of beating the likes of Tyson Fury to a shot at Wilder later this year.
