Ultimate Fighting Championship (UFC) held its traditional pre-fight press conference earlier today at the KeyArena in Seattle, Washington, to help promote this Saturday night's (Dec. 8, 2012) UFC on FOX 5 event, featuring a lightweight title fight between reigning champion Ben Henderson and division number one contender Nate Diaz.

Today, the faced off for the first time.

Also on hand was former UFC light heavyweight champion Mauricio Rua, who will try to keep himself from becoming a stepping stone for top 205-pound prospect Alexander Gustafsson, who looks to use a win over "Shogun" to try and get himself "in the mix."

As luck would have it, they stared each other down, as well. And so, too, did the rest of the main card participants, which are all below for your viewing pleasure.

MMAmania.com will provide LIVE round-by-round, blow-by-blow coverage of the main card action on fight night (Sat., Dec. 8, 2012), which is slated to air at 8 p.m. ET on FOX. The latest quick updates of the live action will begin to flow earlier than that around 3:30 p.m. ET with the "Prelims" bouts on Facebook and FX Channel.
