When Jon Jones rejected an order to fight the UFC's suggested injury-replacement fighter, Chael Sonnen, UFC took the unprecedented step of canceling its entire UFC 151 card, scheduled for Sept. 1 in Las Vegas. UFC officials placed the blame for the cancellation entirely on Jones.
"This is probably one of my all-time lows as being president of UFC," Dana White said.
Jones' scheduled opponent, Dan Henderson of Temecula, tore the medial collateral ligament in his right knee during training and was unable to resume preparations after visiting a doctor.
White wanted to insert Sonnen, the brash former middleweight challenger who lost via second-round technical knockout to champion Anderson Silva on July 7.
White quoted Jones as telling the president, "I'm not fighting Chael Sonnen with eight days' notice," and said Jones' trainer, Greg Jackson, advised that taking on Sonnen "would be the biggest mistake of" Jones' life. Jackson, said White, "is a sport killer."
