Mark Hunt made some waves in the heavyweight division after he knocked out Roy Nelson in the second round with a single uppercut that sent "Big Country" face first to the canvas (video).

Another notable addition to the heavyweight rankings is Matt Mitrione, who debuted on the list after knocking out Derrick Lewis two weeks ago at UFC Fight Night 51.

Miles Jury also managed to move up a spot in the lightweight division after he finished longtime veteran, Takanori Gomi, in the very first round in "The Land of the Rising Sun."

There you have it, another crazy shakeup in the official UFC rankings.

Hunt called for a a fight against top five fighter following his destruction of "Big Country," but now that he occupies that spot, his next opponent has now been dwindled down to four candidates.

You can expect these numbers to change rather quickly as UFC 178: "Johnson vs Cariaso" goes down this Saturday (Sept. 27, 2014) in Las Vegas, Nevada
