Fuel TV's Ariel Helwani reports that Dennis Hallman was seven pounds over weight. Hallman then struck a deal with Thiago Tavares who said he would accept the fight if Hallman could get within three pounds of the 155 pound limit. Hallman could not make that cut and the fight has been called off.

Fuel is reporting that Thiago Tavares vs Dennis Hallman fight is off, Hallman missed weight for the second straight fight...stay tuned for this one.

Time for the big fellas as we head to the heavyweight main event. First to the scale is Antonio "Bigfoot" Silva and he comes in at 266. His opponent, Travis Browne checks in with a Vikings shirt and weighs in at 246.

Silva edges in a little to close for comfort during the staredown and Dana White steps in between the fighters, who do not break eye contact for quite a long time.

On to the welterweight co-main event. Jay Hieron gets a decent reception for his first UFC fight since 2005. Hieron comes in at 170. Jake Ellenberger comes in at 170 as well.

Flyweight title eliminator up next. Firs to the scale Jussier da Silva and he asks for the towel right away, not the best first impression for your UFC debut, but he makes the weight, coming in at 126. John Dodson does a bit of a striptease to get down to his Batman underoos and he weighs in at 126 and seems to have plenty of energy to spare.

On to the FX card. Justin Edwards hits the scale first and comes in at 170.  Josh Neer comes in at 171.

Another lightweight bout is next, Yves Edwards vs. Jeremy Stephens. Edwards comes in at 156, Stephens comes in at 156 as well and oh yeah, he has a rat tail...

Michael Johnson versus Danny Castillo is next. Castillo comes in with the breakaway tux and weighs in at 156. Nothing fancy from Johnson, however he has a nice Jaco track suit on, oh wait, he adds some Viking horns, which the crowd approves of and he weighs in at 156.

Next up are lightweights Shane Roller and Jacob Volkmann. Roller comes in at 156, while Volkmann comes in wearing his Volkmann for President shirt and weighs in at 155.
