Ultimate Fighting Championship (UFC) will once again air an entire fight card TONIGHT (Dec. 8, 2012), this time with UFC on Fox 5: "Henderson vs. Diaz," which will emanate from the KeyArena in Seattle, Washington.

The mixed martial arts (MMA) action will begin around 4:30 p.m. ET with the "Prelims" Bantamweight bout between Scott Jorgensen vs. John Albert that will air LIVE on Facebook.com. The rest of the under card will continue on FX at 5 p.m. ET and run for three full hours up until the FOX main card broadcast at 8 p.m. ET.

Fight fans who live outside the United States -- or who don't get FX in their cable package -- might have a hard time finding a way to watch the "Prelims" bouts; however, the good news is the under card action can be viewed on:

• ESPN (United Kingdom)
• Sportsnet (Canada)
• Combate (Brazil)
• OSN (UAE)
• FUEL TV (Australia)
• UFC.TV (Blocked in U.S., Brazil and India | 41.99 in Canada/ Free in the Rest of the World)

After the "Prelims" conclude, it's on to the main card coverage, which is headlined by a Lightweight championship showdown between 155-pound kingpin, Ben Henderson, and the division's number one contender, Nate Diaz. In addition, former 205-pound champion Mauricio Rua will collide with Swedish upstart Alexander Gustafsson in a number one Light Heavyweight contender eliminator match.

And let's not forget about the emotionally-charged Welterweight showdown between B.J. Penn vs. Rory MacDonald, two fighters at different stages of their careers, but fighting for one shared goal: Supremacy, and in Penn's case, a little bit of legacy, too.
