UFC 151: Jones vs. Henderson (2012)

This was a planned mixed martial arts event that was to be held by the Ultimate Fighting Championship on September 1, 2012, at the Mandalay Bay Events Center in Las Vegas, Nevada. However, the event was canceled on August 23, when the UFC announced Henderson was unable to fight due to injury, and Jones refused to take a replacement fight against longtime middleweight contender, Chael Sonnen.
