Never in 11 years has a UFC event been cancelled but due to some huge issues the event has fallen apart.

The first major thing that stopped event was that Dan Henderson got injuried. Dan tore his MCL in his leg and due to that injury he couldn't get cleared for the fight. And second and the most huge factor making this a very heated debate is that Jon Jones wouldn't accept to fight Dan Henderson's replacement.........CHAEL SONNEN!

Check out the conference call below. Dana White is pissed!
