In what would probably be considered only a mild upset, Forrest Griffin beat reigning UFC light heavyweight champion Rampage Jackson by unanimous decision in a five-round slug fest in Las Vegas.

Both fighters absolutely brought fit or the full five rounds, with Rampage landing a wicked uppercut in the first round before Griffin landed a crushing kick to Rampage's knee in the second round. It was Griffin's second round shot to Rampage's knee that changed the course of the fight, as Rampage simply wasn't the same after.

There's always some disdain for fights that go to a decision, but this was about the best fight money can buy that didn't wind up ending in a knockout. Griffin won on all three judges scorecards.

For Griffin, his career has been on an incredible rise since he became the original winner of The Ultimate Fighter, a TV show which rewards its winner with a UFC contract. Griffin has already beaten Mauricio "Shogun" Rua, Hector Ramirez, Chael Sonnen, Stephan Bonnar, Jeff Monson, and now Rampage Jackson. That's a murderers row of fighters right there.

Anyway, if UFC is smart, and they are, they'll definitely get a rematch between Rampage and Griffin. A lot of people will want to see that.
