The event, which was supposed to be headlined by WBO flyweight champion Anthony Olascuaga's title defense against Andy Dominguez, was canceled Tuesday.

"Due to growing logistical concerns, it is with regret that the event schedule has been canceled," a statement read on IVB's social channels.

"The previously announced card will still be taking place with a new date and venue to be confirmed in the coming days. Full refunds will be made to all that purchased tickets."

Pereira's plan was to break the attendance mark of 132,135 set in 1941 for a fight between Tony Zale versus Billy Pryor in Milwaukee's Juneau Park.

The event, backed by San Francisco Mayor Daniel Laurie, was promoted as “History in the Making" and a press conference was held on a yacht in the San Francisco Bay on May 7. Select tickets starting at $60 were sold, with the other 80 percent of tickets to be given out for free.

Charly Suarez and Gurgen Hovhannisyan were supposed to be featured on the undercard, with promoter Sampson Lewkowicz leading the charge.

The event, assessed in relation to its record-breaking goal, was perceived to be a pipedream from the get-go and met with tremendous skepticism due to its lack of star power, as many predicted the ambitious plans would implode before a single punch could be thrown.
