Anthony Joshua and Jarrell Miller got into it in heated, X-rated press conference

Anthony Joshua and Jarrell Miller aren't even scheduled to fight one another but the two reignited their old feud in a press conference in London on Wednesday night.

Both fighters are competing on a stacked card in Saudi Arabia on December 23, with Joshua taking on Otto Wallin and Miller facing Daniel Dubois, who is coming off a defeat against world heavyweight champion Oleksandr Usyk.

Former world champions Deontay Wilder and Joseph Parker also lock horns, while light heavyweight king Dmitry Bivol squares off against Lyndon Arthur.

But it was Joshua and Miller who were the most vocal in the presser, with the two-time unified world champion telling him to "shut the f*** up" when he began to run his mouth.

'AJ' then said "F**k Jarrell Miller", who he was scheduled to fight in 2019 before 'Big Baby' failed a drugs test.

Joshua also went in on host Dev Sahni when he mentioned about him potentially finally fighting Miller in the future, replying: "You ain't my promoter to judge what I'm gonna do in my career."

Miller was banned for six months and removed from the rankings for testing positive for three different substances ahead of his slated bout with Joshua, who suffered a shock first career defeat to replacement Andy Ruiz Jr.

Upon his return fight against Jerry Forrest, Miller again failed a drugs test and was suspended for a second time.

His last appearance inside the ring was an exhibition fight against Antonio Zepeda in June 2023 and before that he knocked out Lucas Browne in March.

Joshua, meanwhile, is competing in his third fight this year, having beaten both Jermaine Franklin and Robert Helenius at the O2 Arena.
