Jarrell Miller has warned Anthony Joshua he is risking the end of his career if he fights Daniel Dubois.
Joshua, 35, was emphatically stopped in five rounds by Dubois in their fight for the IBF heavyweight title at Wembley Stadium in September and is expecting to challenge him again in a rematch in 2025.
Where prior to losing to Dubois, Joshua was considered on course to finally fight Tyson Fury, a second successive, destructive defeat by Dubois would leave him with fewer options than ever before.
Miller had been on course to fight Joshua in 2019 until his failing a drugs test ruled him out and he was replaced at late notice by Andy Ruiz, who so unexpectedly became the first to defeat Joshua in the fight that transformed Joshua’s decorated career.
The former IBF, WBA and WBO champion defeated Ruiz in their rematch but has since rarely fought with the same conviction that defined him at his peak, and Miller – who was stopped by the improving Dubois late in 2023 – believes that if Joshua again fights Dubois he will lose once again.
“Same outcome,” the 36-year-old told BoxingScene. “‘AJ’s’ still getting knocked the fuck out. I think it definitely does [end his career], but he’s big money – they’re gonna keep milking the cow until there’s no more milk left. Hopefully me and him can get it on before he gets retired.
“Dubois blitzed him. He didn’t think Dubois was that fast, and we all know that AJ don’t got a chin. Instead of waiting for him to run out of gas and get out of rhythm, ‘Let me jump on your ass now’, and that’s what Dubois did.
“I need that fight first [before Joshua retires]. One more loss and he call it quits. One more bad loss – he’s made enough money already. I give everybody the recipe to beating AJ already – he ain’t got no chin; he ain’t got no heart. Put balls in his face, he gonna quit. The same thing’s gonna happen again.
“AJ, you gotta fight me before you retire, you punk bitch.”
Dubois, 27, has made little secret of his desire to again fight Oleksandr Usyk, who he lost to in the fight before his victory over Miller, and Miller said: “I think he’s very capable of having a rematch with Usyk. You know what I mean? But I want that rematch first, before he loses that belt.
“I want my rematch with Dubois. I had a month [to prepare] for that fight; almost had him out of there. I told everybody AJ was going to crack, and that’s what happened.
“He impressed me very well. He hanged in there. His dad [Dave], definitely, was a motivating factor in that fight. But like I said, he fought an out-of-shape, last-minute, ‘Big Baby’.
“He definitely impressed me [against Joshua]. He’s improving every fight, so the one after – Dubois ain’t going to be the same Dubois when I fight him again. Trust me. He ain’t gonna beat the Big Baby.”
