Cowboys Stadium to set indoor record?
"This one, I think, will go over 60,000," Arum said on a conference call with reporters Wednesday afternoon.
The first boxing match in Cowboys Stadium -- between Joshua Clottey and Pacquiao on March 13 -- drew 50,994, the third largest crowd for an indoor fight in boxing history.
"The response to the ticket sales has been great," Arum said. "We're tracking well ahead of where we were of the Clottey fight, so I'm very, very optimistic."
The largest indoor attendance was 63,315 in 1978 when Muhammad Ali fought Leon Spinks at the Louisiana Superdome in a heavyweight title fight.
Arum said it was good that the Dallas/Fort Worth area sports fan was willing to spend more money on the Texas Rangers during their World Series run, proving that the DFW market was thriving and that he's not concerned about adding another big event.
Arum cited the fight's international appeal for the brisk sales, which should draw a diverse crowd. Pacquiao is from the Philippines, where he is an elected Congressman. Margarito is from Tijuana, Mexico.
The outdoor boxing attendance record was set Feb. 20, 1993, in Mexico City. A reported 136,274 came for the Julio Cesar Chavez-Greg Haugen WBC welterweight bout at Estadio Azteca.
