3. Bisping KOs Rockhold (June 4th 2016- UFC 199)
This fight was originally supposed to be Rockhold vs. Weidman 2 for the Middleweight Championship, but Weidman was forced to withdraw.
Bisping who has spent an entire career coming close to earning a title shot, but always coming up short, was not going to turn down the opportunity to step up on short notice. Rockhold would later state that he took the fight lightly, but the fact remains he got knocked out and his title taken.
