Jones, the UFC light heavyweight champion, took to Twitter on Saturday night. He didn't have much else to do after his title defense versus Henderson went down with the 42-year-old fighter's bum knee. "Thanks to @JonnyBones I have no plans tonight," a fan tweeted Jones. "Thanks to the old man and his knee I don't either," the champ responded. Who deserves blame for the cancellation and drama surrounding UFC 151: Jones, Henderson, Zuffa? In the end, probably, all of the above.
