The brash American heavyweight has reignited his war of words with Anthony Joshua, threatening to "end AJ's career once and for all" should they finally meet in the ring. As Miller prepares for his June 7 tune-up fight against Fabio Wardley, he's made it clear this is merely "a pit stop on the road to settling his real score" with the former unified champion.

“100 per cent (there’s unfinished business). I heard he wants the fight still, but his team is telling him no, stay away from Miller. I’m definitely gonna be his career ender if he fights me. He talks a big game when he wants to then he disappears when he gets his ass whooped.

 It’s so funny, every time he gets his ass whooped, he runs to Africa. I want to f**k him up, bad. I want that motherf***ing fight bad, still. I ain’t about the money, I want to f**k him over,” Miller said to IFL TV without mincing words.

The two-time heavyweight king, currently in his ancestral homeland of Nigeria, is laying the groundwork for what could be his final championship pursuit. Now 34, the London-born Olympic legend (2012 gold medalist) has entered camp preparations without yet naming his next opponent - with industry insiders suggesting his team is carefully selecting a path to one last title shot before retirement.

The veteran champion continues to rise above Miller's provocations, maintaining laser focus on his ultimate goal: reclaiming heavyweight gold in his career's twilight years. While a heated showdown with the American would satisfy fans' appetite for drama, boxing pundits' debate whether Joshua would stake his legacy on such a risky final act when more prestigious opportunities may await.
