Anthony Joshua launches expletive-laden tirade at Jarrell 'Big Baby' Miller

British heavyweight Anthony Joshua was involved in expletive-laden exchanges before his face-off with next opponent Alexander Povetkin in New York.

Former Olympic champion Joshua had to square up to another boxer, Jarrell 'Big Baby' Miller, during his meet with Povetkin after the American invaded the stage.

Joshua, who has until now cultivated a clean-cut image rather than engage in the customary trash talk, shouted at Miller: “Who you f------ talking to, shut the f--- up and get off the stage, you little b----. I-ll slap you. Have some respect.”

Miller has wanted to face Joshua - who fights Povetkin in his seventh world title defence at Wembley Stadium on Sept 22.

Miller is ranked at No 3 with the International Boxing Federation and World Boxing Association and remains a viable opponent for Joshua.

Joshua later told Sky Sports: “This is where I’m at right now, I can’t sit down for too long because there’s always people clucking around me feet. I have got to kick them back down.

“People talk about me and see me face-to-face and they still want to talk.

“I defend my titles in the ring time and time again. I just wont tolerate it out of the ring either.

“Anyone is welcome to come and get the smoke as well. Firstly focus on Povetkin and you never know what the future holds.”

Joshua holds three of the four major world titles - the IBF, WBA and World Boxing Organisation - with Deontay Wilder’s World Boxing Council belt between him being undisputed heavyweight champion.

He fights Povetkin as a mandatory bout but Wilder is the opponent he wants.

He said: “It’s one thing me saying it and it’s another me doing it. I’ve secured the date, location, my side has been signed. All we need to do is wait for the ink to dry and the fight is locked in.

“He’s got up until now and January to sign the contract. Unfortunately there was a time scale and it didn’t happen so I have a mandatory fight. I need to secure my destiny of become undisputed heavyweight champion of the world.

“Povetkin is good, a solid fighter, an Olympic champion and I respect him. I respect every fighter. He is a banana skin.

“He has fought people like me all his life, he knows how to slip punches. It’s not the height difference which is the issue, it’s how determined he is and how willing he is.”
