UFC 138: "Leben vs. Munoz" is just around the corner, emanating from the LG Arena at the National Exhibition Centre in Birmingham, England, on Saturday, Nov. 5, 2011.

And that means all the pre-fight festivities, like press conferences (here), weigh-ins (here) and the obligatory staredown pictures that come with them.

Above we have the main event of the evening, featuring Chris Leben vs. Mark Munoz. This is more than just a heated match-up pitting two middleweight players looking to jump into the title picture. It's actually a historic event.

That's because Leben vs. Munoz will be the very first five-round main event non-title fight in UFC history. Say what you will about the fight card as a whole, that's got to count for something.

Staredown pics from Brad Pickett vs. Renan Barao and Thiago Alves vs. Papy Abedi are after the jump. For complete UFC 138 weigh-in results click here. For staredown videos click here.
