Why it matters: The fight was set to be a career-defining homecoming for the undefeated Ipswich boxer at his boyhood club's stadium in the first professional boxing event ever staged at Portman Road.
The details: The 36-year-old Miller will no longer be able to participate in the contest that was marred by controversy when he slapped Wardley during their heated press conference on 7 April.
It is understood the card has not been cancelled, with a different fighter to be called in to replace Miller and face Wardley for the interim WBA heavyweight title.
The bigger picture: Wardley is a lifelong fan of Ipswich Town and vacated his British title in March as he pursues a world title.
"As a proud Tractor Boy born and bred in Ipswich, this is a dream come true for me," Wardley said previously.
"Fighting for a world title at Portman Road means everything to me. I've got a tough opponent in front of me, but that's what I live for."
Miller was originally set to face WBA 'regular' champion Kubrat Pulev but the bout was changed to feature Wardley instead.
The undefeated 30-year-old Ipswich boxer has 18 wins and one draw on his record, with 17 victories via stoppage.
What they're saying: When the bout was initially announced, Wardley had been complimentary about Miller despite his controversial reputation.
"He's a top 10 contender, he's challenged with the big boys before, and I'm in that world title race and I want to prove myself against one of those top-level guys," Wardley said.
"I think he's a perfect fit for that because he brings energy and he brings the fight in simple terms."
Ticket information: The event will still take place at Portman Road, with music superstar Ed Sheeran, also a fan of the Tractor Boys, rumoured to be performing.
The 7 June event remains a historic occasion as the first-ever boxing show at Portman Road, and regardless of who Wardley faces, the homecoming of Ipswich's undefeated heavyweight promises to be a landmark night for the town.
