The event was the second that the organisation hosted in
Northern Ireland, with the first being
UFC 72 in June 2007. However, on 21 October, it was announced that Nelson pulled out due to an injury and the fight was cancelled. Kim was rescheduled to compete at
UFC 207. In turn, a middleweight rematch between former
Strikeforce Light Heavyweight Champion Gegard Mousasi and
Uriah Hall was announced as the new headliner. The pairing met previously in September 2015 at
UFC Fight Night: Barnett vs. Nelson with Hall taking the victory via second round highlight reel TKO in what was considered a huge upset. A lightweight bout between
Ross Pearson and
James Krause was originally booked for
The Ultimate Fighter: Team Joanna vs. Team Cláudia Finale. However, Krause pulled out due to undisclosed reasons. The fight was later rescheduled for this event and was expected to serve as the co-main event. Subsequently, on 26 October, Krause pulled out of the fight citing a torn hamstring. He was then replaced by
Stevie Ray. As a result of the cancellation of
UFC Fight Night: Lamas vs. Penn, a flyweight bout between
Kyoji Horiguchi and
Ali Bagautinov was rescheduled for this event. At the weigh-ins,
Zak Cummings came in at 172.8 lb, almost two pounds over the welterweight limit of 171 lb. As a result, Cummings was fined 20% of his purse, which went to his opponent
Alexander Yakovlev and the bout proceeded as scheduled at a catchweight. A flyweight bout between
Ian McCall and
Neil Seery was scheduled for the event. However, as Seery was weighing in for the event, it was announced that McCall had to pull out of the fight after becoming ill due to the effects of his
weight cut and the bout was scrapped. ==Results==
