UFC 166: Velasquez vs. Dos Santos III

With a 4-2 record since moving from light heavyweight, Tim Boetsch has proven himself to be one of the premier 185-pound fighters on the planet, but he's still hungry for another statement-making victory against CB Dollaway.

Two of the UFC's most exciting lightweights square off at 166 when Gilbert Melendez meets Diego Sanchez. Melendez is coming off a split-decision title loss to champ Benson Henderson and will do whatever it takes to keep this one out of the judges hands.

With 2 KO wins, and his athleticism, Shawn Jordan is prepared to take his career to the next step. Gabriel Gonzaga has been that next step for plenty of heavyweights, and he has sent several back to square one with his ability to finish any opponent.

Two welterweights with a flair for the dramatic, Adlan Amagov and TJ Waldburger meet in the Octagon in a quest for victory and a heart-stopping finish.

Former Strikeforce champion Sarah Kaufman makes her Octagon debut against Jessica Eye. Perhaps the best striker in female MMA, Kaufman has 10 knockouts among her 16 wins. But with a 7 fight winning streak, Eye is ready to go.

Bad blood will boil over into a heavyweight brawl as durable Roy Nelson and undefeated Daniel Cormier clash at UFC 166.
