USA Today's For The Win blog discusses the exchange from the recent Dana White VLOG for Fight for the Troops:

Dwight Howard may be making a quick venue change: From the basketball court to the UFC Octagon. During a backstage visit at a UFC fight in Houston, the Rockets’ big man told UFC president Dana White recently that he’d be willing to go into the cage … for $10 million.

"I would get up there and fight. If I get knocked out, I get knocked out," Howard said. "I’ll get back up one day."

White immediately interjected. "I want to do that pay-per-view when you’re ready, man," he said.
