UFC president Dana White displayed his level of frustration for MMA trainer Greg Jackson during a special media conference call on Thursday when he announced that UFC 151 would be scrapped due to UFC light heavyweight champion Jon Jones not accepting a fight on short notice with Chael Sonnen.

Dan Henderson was forced to pull out of the fight due to a partially torn MCL.

White said Sonnen was the only fighter to accept the bout, but Jones came back and turned it down after talking with Jackson and the rest of his team.

“(Jones) said I gotta sit down and talk to my coaches. Greg Jackson says there’s no way you take this fight on eight days notice; it’d be the biggest mistake of your entire career,” White said. “Wow. Chael Sonnen is a 185-pounder who wants to move up, who hasn’t trained a day for this fight, yet he says he’ll fly (to Las Vegas Wednesday night) to fight the suppose pound-for-pound, third-best fighter in the world. How much faith do you have in your champion, your guy?”

White continued when asked to respond about comments made by Jackson during a radio interview being conducted at the same time. Jackson said he didn’t understand why White was so upset with the decision by Jones.

“I don’t give a (expletive) what Greg Jackson thinks,” White said. “Greg Jackson should never be interviewed by anybody ever again, except a psychiatrist.”
