The UFC canceled its Sept. 1 pay-per-view show Thursday after light heavyweight contender Dan Henderson injured his knee and champion Jon Jones declined a replacement fight with Chael Sonnen.

UFC President Dana White was left furious with Jones and his trainer, Greg Jackson, after the UFC was forced to scrap a major card for the first time in his 11 years in charge of mixed martial arts' dominant promotion.

"This is probably one of my all-time lows," White said. "The one thing that I never thought in a million years would ever happen — it happened."

White said Jones is the first UFC champion ever to turn down a match even on such short notice.

UFC 151 was scheduled for Sept. 1 at Mandalay Bay Events Center in Las Vegas.

Jones agreed to defend his title against former champion Lyoto Machida at UFC 152 in Toronto on Sept. 22 in a rematch of their bout last December in the same city.
