We knew before Jon Jones ever stepped into the cage against Rashad Evans at UFC 145 who his next opponent would be if he won: Dan Henderson.

Shortly after it was officially announced that Jones would be taking on Henderson his next time out, UFC president Dana White revealed that the two would likely be meeting at the impending UFC 149 event. Those plans no longer seem to be intact.

Jones’ manager, Malki Kawa, spoke with MMAFighting this week and revealed that his client won’t be ready to return to training in time to make the date for the UFC’s first Calgary-hosted fight card.

With the event scheduled for July 21, Jones would have just three months turnaround from his recent title defense over Rashad Evans. Jones battled his former rival for five rounds to earn a unanimous decision victory at UFC 145 earlier this month and would like to take more time than that to relax and recover.

Henderson has been on the sidelines waiting for a shot at either the middleweight or light heavyweight titles – whichever one opened up first – since November, when he earned a narrow unanimous decision over Mauricio “Shogun” Rua at UFC 139.
