Miller will represent Joshua's sixth unbeaten opponent since 2015.
Joshua will put his WBO, WBA and IBF belts on the line at the iconic NY venue in what will be his first bout outside Great Britain.
That makes the fighters a combined 45-0-1 with 41 knockouts. "I plan to embrace the culture and leave with an appetite for more".

"I am looking forward to taking on another challenge with a good boxer and a brilliant talker".
Joshua is not only coming across the pond, but he will do so to fight in the hometown of the Brooklyn-born Miller.
Miller is an offensive tackle-sized heavyweight who has surprising athleticism for a man his size. In his last fight, Miller knocked out then-undefeated Bogdan Dinu in the fourth round on November 17.
The 30-year-old will nearly certainly be the heaviest opponent Joshua has faced as a professional having weighed 22st 7lbs in his last contest. The last time Miller weighed under 290 was on November 11, 2017, when he defeated Mariusz Wach while weighing 283.25, which is 39.25 pounds more than Joshua's career high of 254. "It is a dream come true for Jarrell, but it is exactly what we envisioned and what I promised him when I began working with Jarrell in his second professional fight".

He said: 'Myself and Wilder are the current active champions of the world. 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. It's a major statement in the United States market. But Wilder fought to a thrilling split draw with Tyson Fury in December, and a rematch between the two is reportedly set to occur in the first half of 2019.
A superstar who has routinely sold out stadiums in the United Kingdom - including a British-record of 90,000 at Wembley Stadium in London for his 11th round knockout of Wladimir Klitschko in 2017 - the knock by many boxing pundits on the unified heavyweight champion is that Joshua hadn't fought in the United States and needed to do so in order to become a global star.
Joshua is one of the most popular fighters in the world and has drawn crowds in excess of 80,000 in the U.K. Bringing him to fight for the first time in the US will increase his name recognition here and make him into more of a global superstar.More news: Morgan Stanley to buy Calgary-based Solium Capital for $1.1 billion
