Plans to stage the most attended event in boxing history have been announced by live sports entertainment organisation iVisit Boxing (iVB).
San Francisco’s Civic Center Plaza will be turned into an open-air boxing arena with the card being streamed on YouTube on 11 July.
The current record for the largest attendance at a boxing event stands at 135,132 – when Tony Zale and Billy Pryor fought at Juneau Park, Milwaukee in 1941.
“This world-record attempt will belong to San Francisco,” said iVB chief executive Ed Pereira. “It belongs to its fans, its fighters and its communities.”
“San Francisco’s commitment to community and public engagement reflects iVB’s belief that boxing should be built around its fans.”
Despite reports that WBA, IBF and WBC heavyweight champion Oleksandr Usyk and Deontay Wilder are set to fight on the card, BBC Sport understands no agreement is in place for them to meet at this event.
