A knee injury forced Dan Henderson to pull out of the main event at UFC 151 just nine days before he was to challenge for Jon Jones' title in Las Vegas, thus causing the UFC to cancel the entire card.
Jones refused a challenge from Chael Sonnon, citing having received only eight days notice. No main event, no card!
