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.

Darrell Montague makes his Octagon debut at UFC 166 against former title contender John 'The Magician' Dodson. Coming off a decision loss to flyweight champ Demetrious Johnson, 'The Magician' won't be looking to give Montague a warm welcome to the UFC.

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.

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.

Fans of the welterweight division will be in for a treat when perennial contenders Hector Lombard and Nate Marquardt collide in the Octagon at UFC 166.

George Sotiropoulos returns to the Octagon with plenty of unfinished business at 155 pounds. Owner of 7 UFC victories, Sotiropoulos will get a stern test against KJ Noons, who hopes to derail Sotiropoulos' comeback and earn his first UFC win.
