UFC 177: Dillashaw vs. Soto was a mixed martial arts event held on August 30, 2014, at the Sleep Train Arena in Sacramento, California.

[7] However, on August 12, it was announced that bout would be moved to headline UFC 178 after Jon Jones against Daniel Cormier was delayed due to injury.

[8][9] As a result of the cancellation of UFC 176, bouts between Danny Castillo vs. Tony Ferguson, Lorenz Larkin vs. Derek Brunson[10] and Bethe Correia vs. Shayna Baszler were rescheduled for this event.

[15] Due to the many unexpected changes, Joe Rogan began the event's weigh ins show by introducing the crowd to "the haunted UFC card".

[20] Although not included on the CSAC's initial report, Scott Jorgensen ($52,000/$26,000) and Anthony Birchak ($16,000/$8,000) were paid a show purse and win bonus after their respective bouts were scrapped prior to the weigh-ins.
