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 Las Vegas, 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.” About this planned but never realized fight, "Big Dog" Benny Henderson Jr. asked Shelby Walker, “It has been rumored that you may fight Erika Montoya at UFC 51, is there any truth to those rumors?” 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. I haven’t heard anything more from this but my biggest dream would be to fight in the UFC.”

The event was also to be held in Japan, but UFC President Dana White moved it back to Las Vegas. Headlining the card were fan favorites Tito Ortiz and Vitor Belfort.

Dave Herman (born September 3, 1941 in Bryan, Ohio) is a former American collegiate and professional football offensive guard. He played collegiately for Michigan State University. He spent his entire 1964-1973 professional career with the New York Jets.

Dave Herman was the starting right guard for the New York Jets during the 1968 season. His fellow starting offensive linemen that year included left tackle Winston Hill, left guard Randy Rasmussen, center John Schmidt, and right tackle Sam Walton.

In preparation for Super Bowl III, Jets coach Weeb Ewbank moved Dave Herman from right guard to right tackle to defend against Baltimore Colts' defensive lineman Bubba Smith. Bob Talamini replaced Herman at right guard and Sam Walton, a rookie, was benched.

Herman's ability to neutralize the pass rush of Bubba Smith enabled Joe Namath to enjoy a solid game passing, hitting on 17 of 28 passes. It also helped open the running lanes for Jet fullback Matt Snell, who rushed for 121 yards as the Jets beat the heavily favored Colts 16-7.
