The official weigh-in event for UFC on Versus 3: "Sanchez vs. Kampmann" took place today (Wednesday, March 2, 2011) from the Kentucky International Convention Center in Louisville, Kentucky.

And while you can typically count on at least an intense staredown when Diego Sanchez is involved, even he was even-tempered when it came time to square off.

All involved hit their respective weights for the show, with only a couple fighters needing to strip to their birthday suits to hit their marks. Let's hope they're saving their energy for the event tomorrow night.

"Sanchez vs. Kampmann" will feature a match-up between reinvigorated welterweight Diego "Nightmare" Sanchez and 170-pound top contender Martin "Hitman" Kampmann.

Also on tap for March 3 is a middleweight mash-up between Mark Munoz and C.B. Dollaway while Brian Bowles and Damacio Page will square off looking for their first victories as Zuffa employees.
