Saturday brings us our first UFC event of 2012 with UFC 142, the promotion's return to Rio, Brazil, headlined by Featherweight Champion Jose Aldo vs. Chad Mendes with Vitor Belfort vs. Anthony Johnson in the co-main event.

While you can see the Countdown To UFC 142 show on Fuel TV starting at 10 PM EST Wednesday, the UFC has also made the entire video available to watch online in two parts.

Part one focuses on Aldo vs. Mendes with the usual training footage and background from both camps.

For the second half of the Countdown special, join us after the jump.

Part two focuses on Belfort vs. Johnson.

Bloody Elbow will have coverage of UFC 142 throughout the weekend, kicking in high gear on Thursday with the betting odds and the pre-fight press conference, Friday's staff predictions and the live weigh-ins to Saturday's event day with the usual primers, live play-by-play and then recaps and reactions from the night.
