The promotion was initially targeting a middleweight bout between former interim UFC Middleweight Championship challenger (as well as 2000 Olympic silver medalist and former world champion in freestyle wrestling) Yoel Romero and Paulo Costa to serve as the event headliner. The pairing was previously scheduled to take place at UFC 230 and then again at UFC Fight Night: Cejudo vs. Dillashaw but was scrapped each time for injuries to both fighters.[3] However, on March 7, the promotion elected to replace Costa and arrange a rematch between Romero and former Strikeforce Middleweight ChampionRonaldo Souza to serve as the event headliner.[5][6] The two met previously in December 2015 at UFC 194 with Romero winning via split decision.[7] It was then reported in early April that Romero pulled out of the bout due to pneumonia.[8] While not officially announced by the promotion, Costa was initially expected to replace Romero.[9] However, Costa indicated that the three week lead time would not be enough for him to adequately prepare, so he declined.[10] Souza ultimately faced Jack Hermansson in the main event.[11]
A welterweight bout between Alex Oliveira and Li Jingliang was scheduled at this event. However, it was reported on March 23 that Li was injured and was forced to pull out of the bout.[19] He was replaced by Mike Perry.[20]

However, it was reported that Souza pulled out of the bout citing an ankle injury and she was replaced by current Invicta FC Strawweight Champion Virna Jandiroba.[21]
A lightweight bout between Gilbert Burns and Eric Wisely was scheduled for the event.[22] However, it was reported on April 18 that Wisely pulled out of the bout, citing injury. He was replaced by newcomer Mike Davis.[23]
