Last month Jose Aldo had to pull out of his scheduled featherweight title defense on August 2nd, and after the UFC was unable to find a main event caliber fight, the entire event has been postponed. UFC.com released an official statement this evening:

The UFC® has announced that the UFC 176 Pay-Per-View event scheduled for August 2nd will be postponed. The featherweight championship fight scheduled to headline the event at STAPLES Center in Los Angeles was dropped from the card last week when champion Jose Aldo sustained an injury making him unable to defend his title against No. 1 ranked featherweight Chad Mendes.

The featherweight championship fight between Aldo and Mendes is expected to take place later this year and all other fights previously slated for UFC 176 are being rescheduled for upcoming cards. The August 30th Pay-Per-View event will remain titled UFC®177: DILLASHAW vs. BARAO II at the Sleep Train Arena in Sacramento, Calif. Tickets for UFC 177 go on-sale Friday, July 18th.

As the STAPLES Center event will no longer take place, ticket refunds will be offered at the original point of purchase. If tickets were purchased from AXS via http://www.axs.com or Purchase By Phone, refunds will be received automatically via AXS. Tickets purchased from the STAPLES Center box office can be refunded there, beginning Wednesday, July 9th. Those who purchased tickets at any other outlet should reach out to that original point of purchase and contact them directly for a refund.

The UFC has only ever canceled one event, which was UFC 151 that was scheduled for September 1st, 2012 in Vancouver. The main event was planned to be Jon Jones vs. Dan Henderson, but Henderson pulled out of the fight with an injury. Chael Sonnen offered to fight Jon Jones last minute, but Jones refused and the event was cancelled.
