Chael Sonnen was almost back. Jon Jones will defend his title at UFC 152 (Now the new UFC 151) against Lyoto Machida. Dan Henderson had to pull out with a partial tear of his ACL. Chael Sonnen was offered the title fight and accepted. Jones then turned down the fight with Sonnen. The UFC has decided to cancel the event. As Dana White pointed out, this is the first time that the promotion has canceled an event in 11 years.

Sonnen most recently lost to Anderson Silva at UFC 148. Following that fight, Sonnen announced a move to light heavyweight and almost immediately tried to start talking his way into a title fight with Jon Jones.

It worked. But Jones turned it down. This is incredible. Jones was already taking a beating from fans and media.

Update: This also says a lot about the quality of the current UFC cards. Instead of go on with a PPV without Jon Jones, the UFC has decided to outright cancel the event.
