One of the biggest underdogs in the UFC today just KO'd Luke Rockhold to win the middleweight belt

New champ!

After Luke Rockhold (15-6) handed Michael Bisping (29-7) his first submission loss of his career back in November 2014, the Brit got his much-deserved payback to claim the UFC middleweight crown at UFC 199 in his first-ever title bout.

Bisping gave one of the greatest pre-fight promo interviews of all-time ahead of the bout, calling his shot and knocking the champ out on 17 days notice.

Going into the fight, Rockhold was -900 according to Best Fight Odds.

Absolutely unreal.
