During Thursday’s UFC on FX 8 pre-fight press conference, Vitor Belfort did that thing he loves to do where he held his right fist out to Luke Rockhold‘s chin during their photo-op staredown. Luke was not amused. So, after the two headliners weighed in today at Arena Jaragua in Jaragua do Sul, Santa Catarina, Brazil, Rockhold just walked straight through Belfort’s fist-pose, making body contact with the Brazilian fighter. Belfort shoved Rockhold, and Bootleg Dana had to separate them.

Video of that incident is above, and the full “Belfort vs. Rockhold” weigh-in results are after the jump. Be sure to come back to CagePotato.com tomorrow night at 9 p.m. ET for our liveblog of the main card!

Props to our pal Rose Namajunas and Sucker Punch Entertainment for sending us some behind-the-scenes footage of Thug’s fight-week activities in the days leading up to Invicta FC 5. You will see: Rose working pads with Trevor Wittman. Rose peeling potatoes while wearing the traditional head-wrap favored by grandmothers the world over. Rose on the phone, discussing mean-mugging strangers at the grocery store for the interview that she gave us two days ago. (Dude, I’m on the other end of that phone. Bloooooosh.) And so on. Check it out, and follow Rose on YouTube and Twitter!

After the jump: Rose, Cyborg, Karate Hottie, Jessica Penne, Bec Hyatt, and all the rest will be hitting the scales today for the Invicta FC 5 weigh-ins, beginning at 6:30 p.m. ET / 3:30 p.m. PT.  Watch the action live in the player below…

All 24 fighters on the surprisingly-awesome UFC on FUEL 7 card will be hitting the scales shortly in London. You can watch the weigh-ins live in the player above starting at 11 a.m. ET/ 8 a.m. PT; results will be updated after the jump. And be sure to come back tomorrow afternoon beginning at 3 p.m. ET for our liveblog of the FUEL TV main card, alright?

(It was at the UFC 153 pre-fight press conference that Stephan Bonnar revealed his true gameplan to defeat Anderson: G.T.L.) 

All the fighters for tomorrow night’s UFC 153 event are scheduled to hit the scales starting at 3 p.m. EST this afternoon from the HSBC Arena in Rio de Janeiro, Brazil, so make sure to swing by the Tater to check out all the intense, barely-clothed staredowns you could ever ask for. Did that come off as gay? Because we didn’t mean for it to come off as gay; not that there’s anything wrong with that.

Anyway, a string of injuries (go figure) and a good old fashioned case of hepatitis have dramatically altered the face of UFC 153, leaving us with a main event matchup that, when viewed through an incredibly narrow and skewed lens, is almost plausible. So swing by this afternoon to see whether or not Stephan Bonnar will piss himself after he realizes just how big of a mistake he has actually made, whether or not Anderson Silva will come dressed as a Jabbawockee again, and whether or not the Brazilian audience will still be donning their “I fucked Chael Sonnen Last Night” t-shirts. Also, be sure to swing by tomorrow at 10 p.m. EST for our official liveblog of all the action!

(Yeah, and Sarah Kaufman scored the cover of Respectful Canadians Weekly, but does anyone seem to care? Nooooooo.)

While we don’t expect the kind of forehead-jockeying that Ronda Rousey got into with Miesha Tate back in March, it’ll be interesting to see what kind of shape the Strikeforce bantamweight champion is in going into her title defense against Sarah Kaufman tomorrow night. You can watch the weigh-ins for the entire Strikeforce: Rousey vs. Kaufman card in the player after the jump, live from San Diego. The first fighter will hit the scale at 6:45 p.m. ET / 3:45 p.m PT. Let us know what you think. Here, we’ll give you a discussion topic: The male fighters are a complete afterthought for this event — does that say more about the progress of women in MMA, or the supporting card‘s utter mediocrity?

All fighters made weight at last night’s weigh-ins for The Ultimate Fighter 15 Finale, which goes down live on FX tonight at the Palms Casino Resort in Paradise, Nevada. The evening was surprisingly absent of anything even resembling intensity, as many of the fighters (especially those on the undercard) seemed more like they were trying to one-up each other in terms of how goofy a stance they could strike for the cameras. As Yves Edwards would surely tell them, the key to a great weigh in photo is simplicity. And a bag of KC Masterpiece potato chips.

Will Martin Kampmann finally score a victory over a top contender that has eluded him ever since his win over Carlos Condit? And will the winner of Kampmann/Ellenberger receive a title shot in the clusterfucked welterweight division? Who will be crowned “king shit” of what may have been the least memorable season of The Ultimate Fighter in the show’s history?

For the answers to all these questions and more, make sure to swing by CP tonight, where our very own writer/ass-kicker Elias Cepeda will be liveblogging all the action starting at 9 p.m.

Join us after the jump for the video and full weigh-in results. 

Weigh-ins for UFC 131 are kicking off today at 5 p.m. ET / 2 p.m. PT, at the Jack Poole Plaza in Vancouver, British Columbia, Canada. Check out streaming video of the festivities after the jump, courtesy of the UFC. We’ll plug in the weight totals below the video player after things wrap up. How emaciated will Kenny Florian be at 145? Will Shane Carwin have the same beastly intimidation factor now that he’s slimmed down below the 265-pound limit? What does Vagner Rocha look like, anyway? All will be revealed…
