The Gypsy King is set to defend his WBC heavyweight belt against the Body Snatcher next month at Wembley Stadium on April 23 in an all-British title fight.
Fury, 33, is currently in the middle of an eight-week training camp in Morecambe having recently reunited with head trainer SugarHill Steward after returning home from the United States.
The Ring Magazine’s No1-ranked heavyweight in the world has already drafted in a few big names to help him get ready for Whyte.
David Adeleye and Martin Bakole have both been involved in sparring sessions with Fury in recent weeks.
But now, he has also turned to Miller, who was originally supposed to fight Joshua in 2019 before a drugs ban scuppered those plans.
It comes after the Nevada State Athletic Commission unanimously agreed to keep ‘Big Baby’ suspended from boxing until June 16 at a hearing in Las Vegas last week, meaning he will be free to apply for a professional license this summer.
Miller, 33, is apparently chomping at the bit to get back in the ring having not fought since his knockout win over Bogdan Dinu in November 2018.
And the New York native’s promoter Dmitry Salita remains convinced Fury vs Miller will happen at some point later down the line once he has made a successful return to the sport.
In an interview with The Sun, the Salita Promotions chief said: “He is getting back in shape with a mind set to be the best in the division.
“He wants to be an American heavyweight champion of the world from Brooklyn, New York. We haven’t had that in a long time.
“Jarrell always did kickboxing training even for his boxing fights.
“It helps him get in shape and maybe one of the reasons why he is so athletic and flexible in the ring for a heavyweight.
“That fight may be the biggest heavyweight promotion in a long time. It can be very exciting.
“One step at a time but that would be tremendous.”
He added: “I believe Jarrell learned his lessons and knows that he has several years to make a mark in the division.
“Positive, responsible action inside and outside the ring is what is most important and something that fans will look at, can’t blame anyone for that.”
