UFC 87 had the biggest live gate in Target Center history according to Steve Cofield:
The attendance at the Target Center was 15,082. The gate of $2.2 million set a new arena record surpassing a Billy Joel/Elton John show.
The Minneapolis Star-Tribune's Myron P. Medcalf notes that a diverse crowd was on hand to help set the record:
As surprising as [Roger] Huerta's performance in front of his hometown crowd was, the variety of fans that came out to watch was just as shocking.
Fiftysomethings sporting "Death Clutch" T-shirts, women cheering louder than their tough-guy boyfriends and the loyal flock of adrenaline-driven young males that have helped the UFC become a $1 billion company were all there.
One fan even sat with an IV hooked up to his veins, while he watched the fights in the front row.
