Deontay Wilder and Tyson Fury are struggling to sell ticket for their heavyweight world title fight, according to Eddie Hearn.
The pair will clash for the American’s WBC belt at the 16,000-capacity Staples Centre in Los Angeles on December 1.
But Hearn, who promotes Anthony Joshua , claims the fight will not be a big draw.
“They’ve only sold 8,000 tickets in a 19,000 arena,” he told Boxing Scene .
“They haven’t even opened the top tier. That’s how big their drawing power is. We’ll see how the pay-per-view numbers do. If they’re big names, they’ll do a million buys.
“I’ve said it before – if they do a million buys and show us that they are a draw then we have to accept that and we have to say, ‘No, fair play. You’re bringing a lot to the table.’
“At the moment, all I’m seeing is empty seats in the Staples arena. And that’s not a good look with three weeks to go before the supposed biggest fight in the heavyweight division.”
Hearn had been negotiating with Wilder’s team about a unification clash with Joshua at Wembley but was unable to agree terms.
Joshua instead fought – and knocked out – Alexander Povetkin while Wilder will face Fury.
The two champions could instead clash on April 13 at the national stadium – unless Fury causes an upset.
Meanwhile, Joe Joyce has joined the card.
The Olympic silver medallist will face Joe Hanks in a 10-round heavyweight fight.
Fellow heavyweight Luis Ortiz takes on American Travis Kauffman while Jarrett Hurd returns for his first fight since unifying the super welterweight division earlier this year to defend his IBF and WBA titles against British Commonwealth champ Jason Welborn.
Hurd, who edged Erislandy Lara in a leading candidate for Fight of the Year in April, will enter the ring for the first time since undergoing rotator cuff surgery as he targets another title unification in 2019.
