Meanwhile, the 29-year-old is excited about making his American debut.
"June 1st I am heading to The Big Apple and I plan to embrace the culture and leave with an appetite for more," he said in the official press release.
"It has been an honour and a blessing to fight at some of the best venues in the World at home in the UK, not least Wembley Stadium, but the time has come to head across the Atlantic and defend my Heavyweight titles in the USA.
"I am looking forward to taking on another challenge with a good boxer & a brilliant talker, it will be an exciting fight, I will leave nothing to chance and plan on dismantling Miller in style to make my mark."
Promoter Eddie Hearn believes June 1st will be the moment the world witnesses 'AJ'.

"AJ has created an incredible 'Lion's Den' atmosphere in the UK and we plan to bring that energy to New York on a card that will be stacked with British vs. American talent.
"When you look at the Heavyweight greats that have graced the renowned 'Mecca of Boxing' the names of Ali, Frazier, Marciano and Tyson stand firm and June 1 will be a moment when the World will witness AJ's turn."
