"Chael didn't know anything about it. He had definitely not been training at all. My guys told me that Greg Jackson said in an interview that Chael was down training with me and getting ready for the fight and knew I was hurt. It was nothing like that at all.. He wasn't even down here... Ultimately it was [Jon Jones'] decision not to take a fight with Chael. I don't think it's unfair that he's been blasted like that. All I know is, that's not the decision I would've made. Obviously he has his own reasons. I can't think of any reason why I wouldn't take a fight like that. Other than being injured, if I'm healthy, in shape and ready to fight that day, it doesn't matter who they want me to fight. I'll fight, especially if I'm champ." -Dan Henderson via MMAFighting.com
Dan Henderson refutes claims recently levied by Jon Jones' head trainer Greg Jackson, who asserted that Henderson informed Sonnen of his knee injury weeks ago, giving Sonnen time to train for Jones before Jones knew he was fighting him.
Jackson's claim seems rather silly given that Henderson wasn't training with Sonnen at the time and neither fighter had any idea if the UFC would even allow Sonnen, who is a middleweight, to move up to light-heavyweight to face Jones.
Aside from that, number one light-heavyweight contender Lyoto Machida was next in line for a title shot and niether camp could have known beforehand that the Brazilian would turn the fight down. In fact, it's likely that the UFC had a list of fighters it waded through as possible replacements for Henderson before considering the possibility of moving down a division and asking Sonnen to step in.
It seems more likely that Jackson's conspiracy theory is an attempt to minimize the criticism his fighter has taken over the past week for the cancellation of UFC 151, by pointing the finger somewhere else.
