One previous world champion is out of the picture after a knockout loss.

ANTHONY JOSHUA has two backup opponents lined up for his Wembley homecoming, despite speculations about fighting Daniel Dubois.

AJ returns to the United Kingdom in September, and Saudi boxing chief Turki Alalshikh will promote the show.

Anthony Joshua is set to return in September at Wembley.

Dubois is currently the frontrunner for the stadium sellout, having defeated Flip Hrgovic to win the “interim” IBF title.

However, Deontay Wilder defeaters Joseph Parker and Zhilei Zhang are also in the running to welcome Joshua back to British boxing lands.

Promoter Eddie Hearn told Boxing Scene: “Ultimately, His Excellency will select who the opponent is, with me, Josh, and 258 [Management], but the aim for ‘AJ’ is to become world champion again.

“If Dubois fights for the IBF title, he’s probably the frontrunner; if the belt isn’t on the line, it might be Zhang or Parker.

“Those three, I think, are decent names, but no decision’s been made yet, and I don’t think it will be for another week or so.

“There’s a press conference on the 26th of June, and that’s when we’ll announce, but either or any of them – we don’t really care.”

Parker, 32, beat Wilder, 38, in December but is yet to return since.

And Zhang, 41, looks to have ended the American former WBC champ’s career with a KO win in Saudi.

The same night, Dubois, 26, stopped Hrgovic, 32, to become mandatory for the world title.

Oleksandr Usyk, 37, was expected to be stripped of the IBF title following victory over Tyson Fury, 35.

But there is hope he will retain the belt to defend it in their December 21 rematch.

Although Hearn is lobbying to have it vacated for Joshua, 34, to challenge for in the summer against Dubois.

Daniel Dubois is frontrunner to fight Joshua next.

Joseph Parker and Zhilei Zhang are also in the running.
