The only thing this should do is make UFC 151, if it happens (which appears unlikely), that much more anticipated.

From Yahoo…

As Kevin Iole reported, UFC 151 has been canceled. The show, scheduled for Sept. 1, was supposed to feature Jon Jones’ title defense against Dan Henderson. Because Henderson sustained a knee injury and Jones turned down Chael Sonnen as a replacement, the entire Las Vegas event has been scrapped.

Jones will go on to fight Lyoto Machida at UFC 152 in Toronto while Henderson rehabilitates, but the card had 10 other fights featuring 20 other fighters. Though the fights will likely be put on other, future cards, moving a fight can severely affect their finances.
