Mandalay Bay Events Center was left with no UFC 151 to promote after the scheduled Sept. 1 event was cancelled Thursday due to an injury to Dan Henderson.
Henderson partially tore a medial collateral ligament in his right knee. UFC president Dana White said light heavyweight champion Jon Jones declined to fight Chael Sonnen, whom he proposed as a replacement for Henderson. That would have kept the show alive, but White said when Jones wouldn’t agree to meet Sonnen, he had no choice but to cancel the show.
Jones agreed to fight Lyoto Machida on Sept. 22 at UFC 152 in Toronto. It is a rematch of the main event of UFC 140, which Jones won by choking out Machida in the second round.
Henderson said he injured his knee while defending a takedown in practice. He said it won’t require surgery, but doctors advised him to stay completely off of it for three weeks. He said the knee “is pretty unstable right now.”
