For the first time in his tenure as UFC president, Dana White was forced to cancel an entire card today after Dan Henderson dropped out of UFC 151 with an injury, and Jon Jones refused to fight a replacement opponent, Chael Sonnen. At a news conference, White said he was "disgusted" with Jones' decision not to fight Sonnen on short notice, saying, "We've never, ever had a fighter refuse to fight someone." The next UFC fight, UFC 152 is September 22 in Toronto, where Jones will face Lyoto Machida.
