A Bantamweight Championship rematch between current champion T.J. Dillashaw and former champion Renan Barão was expected to headline this show. Their first fight, contested at UFC 173, ended in a fifth round TKO victory for Dillashaw. However, the day of the weigh ins, Barão had to be admitted to the hospital as a result of his attempts to cut weight. Dillashaw faced UFC newcomer Joe Soto in the main event. Subsequently, Soto's opponent, Anthony Birchak, was removed from the card entirely.
Scott Jorgensen was expected to face Henry Cejudo at the event. However, Cejudo pulled out of the bout on the day of the weigh ins due to complications trying to cut weight.
Due to the many unexpected changes, Joe Rogan began the event's weigh ins show by introducing the crowd to "the haunted UFC card". Due to the several last minute cancellations, the event took place with only eight bouts on the card, making it the smallest UFC PPV event, since UFC 72 in 2007.
