Dan Henderson has been forced off the UFC 151 card due to a medial collateral ligament tear in his right knee, according to a Yahoo! Sports report.
To make matters worse, Jon "Bones" Jones turned down Chael Sonnen as a replacement, which resulted in the scrapping of the entire Sept. 1 card that was slated to take place at the Mandalay Bay Events Center in Las Vegas, NV.
"We've never had a situation where this happened before, where a champion wouldn't step up to fight," UFC President Dana White said of Jones' decision to not fight Sonnen.
"It's unbelievable to me that he wouldn't take that 'the show must go on' attitude," Henderson said of Jones. "If there was any way I could have gone, and any way I thought I could give myself a chance to win, I would have done that."
