UFC President Dana White announced Thursday UFC 151, scheduled for September 1 in Las Vegas, has been canceled.
Dan Henderson, a challenger for the light heavyweight title, was forced to withdraw from his match with champion Jon Jones because of a knee injury. White said this is the first time in the 11 years he's been in charge of the promotion a major card has been canceled.
"This is probably one of my all-time lows as being president of UFC," White said. "Dan Henderson tried to train, he continued to work out and saw a doctor, but there was nothing we could do to save that fight.
Jones declined to fight Chael Sonnen, who would've replaced Henderson in the main event.
"As of 8pm (Wednesday) night, we thought we had a fight fans would love to see," White said. "Then at about 9pm the one thing I never thought would happen in a million years happened. Jon Jones said, 'I won't fight Chael Sonnen on eight days notice'. That has never happened in the history of the UFC, a guy who is a champion, and a guy who is supposed to be one of the best fighters in the world, pound-for-pound, refuses to fight."
Jones will now fight former champion Lyoto Machida on September 22 in Toronto in UFC 152.
