Roy Nelson walked to the UFC 159 octagon to the sweet sounds of Bruce Springsteen ripping through “Born in the USA” on his way to knockout Frenchman Cheick Kongo.

Meanwhile, in the crowd, a couple of guys were having a slight disagreement over seating and who had a better Tap Out shirt. Eventually things came to blows and bodies started hitting the Prudential Center floor.

As you can see, the classy New Jersey MMA fans also threw, what looks to be, beer on the fan fighters. Those ejected missed Michael Bisping beat Alan Belcher and Jon Jones thump Chael Sonnen.
