Gentlemen, start your engines.

Ultimate Fighting Championship (UFC) President Dana White likes to go big, or go home. In this case, he may be able to do both. The leader of the world's preeminent mixed martial arts (MMA) organization recently told the Las Vegas Review-Journal that he has a handful of fights capable of pulling off a massive outdoor event.

How massive?

Try the 132,000 seats inside the Las Vegas Motor Speedway, a venue that White insists could work, according to the report, with the right weather -- as well as the right fights -- as early as September. And that's just fine with Speedway President Chris Powell, who said the pairing "makes sense."

Tell that to the fans in the bleachers.

White has long flirted with the idea of a stadium show, including a fizzled fantasy fight between Brock Lesnar and Fedor Emelianenko that was "right there" back in 2012. Other venues on the promotion's radar include a soccer stadium in Brazil (see his full list here).

The promotion had no problem setting the North American attendance record at UFC 129: "St. Pierre vs. Shields" in Toronto, Ontario, Canada, which drew an astounding 55,724 fight fans. To fill the Las Vegas Motor Speedway, however, it would need nearly three times that amount.

Can anyone think of a fight that possibly could do it?
