Anthony Joshua received his latest threat from Deontay Wilder this week.
The Bronze Bomber made an appearance on ESPN’s Sports Nation in which he vowed to end Joshua’s career.
"Joshua, let's make this fight happen man," Wilder said.
"This is one of the biggest, most exciting fight in the world history. We could make records, we could set history on the time of the fight whenever it happens.
"I'm ready, I don't know about you. You've had it easy, it's been breezy for you.
"You're ready to fight low opposition and get paid millions of dollars and you don't want that gravy train to end, but I am the man that's going to end your career."
Yet Wilder isn’t the only heavyweight eager to face the IBF, WBA (Super) and IBO champion.
Joshua has received challenges from WBO champion Joseph Parker and from Tyson Fury, who is returning next year after a lengthy hiatus from the ring.
And that’s not all. American heavyweight Jarrell Miller, who is on course for a world title shot after defeating Mariusz Wach last weekend, has said he wants to expose Joshua’s “glass chin”.
"I think either the next fight, or one fight [away] for sure," Miller told Sky Sports when asked about the Joshua fight.
"Yeah most definitely he's got to get through me first, which he won't. I'm like a big roadblock.
"He's full of cr*p, because he's said already he doesn't want to go to America right now to fight. He's said he doesn't want to go to Vegas and fight any time soon.
"He's got to get his story straight. One minute he wants to fight Deontay, then he wants to come to America. I don't know?
"He's really hyped up. Muscles don't save your chin. We all know his chin is definitely glass and it's a matter of time before a fighter will expose him, and I hope I'm the one to do it."
Miller wants Dillian Whyte next
Miller, who boasts an unbeaten 21-1-0 record and is nicknamed ‘Big Baby’, wants to fight Dillian Whyte before taking on Joshua or Wilder in a world title bout.
"Yeah, I think Dillian Whyte would be the perfect guy to knock the hell out," the New Yorker continued.
"He fought a taxi cab driver on his American debut that no one really cared about.
"I think this would be an awesome fight, for me and Dillian to headline in April."
The Americans aren’t afraid to run their mouths, are they?!
