UFC 51: Super Saturday was a mixed martial arts event held by the Ultimate Fighting Championship on February 5, 2005 (Super Bowl weekend) at the Mandalay Bay Events Center in the Las Vegas suburb of Paradise, Nevada.

The event was broadcast live on pay-per-view in the United States and Canada, and later released on DVD.

Loretta Hunt, news editor for Sherdog.com, reports, "I know for a fact the UFC was considering a female bout between Erica Montoya and the late Shelby Walker a few years ago.

Walker replied, "Yeah there is truth to those rumors, it has been talked about a lot and when I asked Dana White if he was going to put us on the show he said possibly, so that is where it stands right now.

"[3] The event was also to be held in Japan, but UFC President Dana White moved it back to Las Vegas.
