That's around 4,000 away from a sellout for the first boxing match at the $1.2 billion stadium.
Promoter Bob Arum says he's not sure whether people are coming to see Pacquiao -- widely considered the best boxer, pound per pound -- or this showplace facility, which Arum called "the greatest venue in the world."
Arum said he's eager to hold more fights at the home of the Dallas Cowboys. He said on a conference call that Kelly Pavlik, Julio Cesar Chavez Jr. and other boxers will be at the fight in hopes of getting to become headliners there.
Cowboys owner Jerry Jones said his stadium becoming a top destination would boost the sport of boxing.
