As an appetizer to tonight’s UFC 155 pay-per-view blowout, the UFC has slated four promising preliminary matchups on FX, featuring battle-tested sluggers (Melvin Guillard vs. Jamie Varner, Brad Pickett vs. Eddie Wineland) and streaking rising stars (Erik Perez vs. Byron Bloodworth, Michael Johnson vs. Myles Jury), all looking to close out 2012 with a bang, bro.

Handling the liveblog for this leg of our journey will be Anthony Gannon, who will be jotting down round-by-round results after the jump beginning at 8 p.m. ET / 5 p.m. PT. Refresh the page every few minutes for all the latest, and if you’re watching along with us, shoot us your own thoughts in the comments section.

(Update: The video was stuck on auto-play, so we moved it after the jump…)

Courtesy of Spike TV, here’s the cast unveiling video for TUF 13, which premieres on March 30th. Among the 14 welterweight hopefuls, there are fewer well-known names compared to recent seasons. I know who Shamar Bailey is because of his stint with Strikeforce, while undefeated KOTC standout Myles Jury — 9-0, all wins by stoppage, eight in the first round — has also been on my radar. But other than that, the cast is mostly made up of unknowns, with no obvious ringer in the mix. On the other hand, there also isn’t a lot of crazy hair in this video, which suggests that maybe these guys are more serious about fighting than camera time. That’s a good sign. A complete cast-list is after the jump…
