Queensberry Promotions, Wardley's promoter, is persistent on finding a high profile fight for the WBA No. 1 contender. And it looks like there are several suitors open to stepping up against the 30-year-old.
Boxing Scene is reporting that Australia's Justis Huni, top ranked heavyweight Filip Hrgovic and Michael Hunter are in the running to replace Miller, with the Australian leading the way.
Huni (12-0, 7 KOs) is currently unranked by the WBA, but he hold the WBO "global" title. The 26-year-old is coming off a 2nd round stoppage over Shaun Potgieter on Jan. 8th. If he steps in, it would be his second bout of the year and a major jump in competition.

Hrgovic (18-1, 14 KOs) has already stepped in on late notice this year, beating Joe Joyce by unanimous decision earlier this month on April 6th. He is also the highest ranked out of all the potential replacement, at No. 6 on the Ring Magazine heavyweight rankings.
Hunter (24-1-2, 17 KOs) is currently ranked No. 2 in the WBA rankings, right behind Wardley. He has also been in talks to fight 43-year-old Kubrat Pulev.
Wardley is coming off a first round knockout over Frazer Clark in their rematch on Oct. 12th, 2024. He is an ascending prospect who is on his way to following in the footsteps of Anthony Joshua and Daniel Dubois as the next great British heavyweight. If he can get a significant win on June 7th, he will inch closer to a world title fight.
