Source: Quinton Jackson leaving UFC because of Dana White Looks like Dana is the real reason Jackson wants out the UFC. I can't blame him for it. Even though i like Dana at times, he too outspoken. He really shouldn't talk trash about fighters on the media like he does so often every time one pisses him off. Its enough pressure been a fighter last thing u need is the president putting u down in front of the world. It's really unprofessional.
