Ben Shalom believes that Joseph Parker and Joe Joyce could still fight one another despite talks collapsing.
The initial failure led Joyce to fight Christian Hammer last weekend, claiming a routine fourth-round stoppage over his German opponent.
Parker is still in the market for another fight to follow up his well received double-header series with Derek Chisora, and the former WBO champion could yet earn another shot at a title, according to Shalom.
"I think there is [a chance the fight can still happen]. I've got a lot of respect for Frank [Warren, Joyce's promoter]," Shalom told Sky Sports.
"Joseph Parker was being almost told that he was avoiding fights and he was avoiding this and I wanted to make it clear that he wasn't.
"Look at Joseph Parker's resume, he's never avoided a fight in his life. Joseph asked us to put in that offer, we put in that offer, it's a huge amount of money. It's a huge opportunity for Joe [Joyce] as well, we feel.
Shalom believes there are other options, saying: "I want him out at the end of September, early October. We're looking at Otto Wallin, we're looking at Dillian Whyte, he wants Martin Bakole. He's looking at a lot of fights.
"He'd like Joe Joyce and Dillian Whyte, they're his top two priorities. If he can't get them, he'll fight anyone.
"He's extremely well-positioned with the WBO, extremely well-positioned with the WBC and I think he will fight for a world title again. That's the aim."
