A bout between Raphael Assunção and T.J. Dillashaw was briefly linked to this event. However, the pairing was delayed and will take place at a later event this year due to a minor medical issue for Assunção. Godofredo Pepey was expected to face Sam Sicilia at the event. However, Pepey pulled out of the bout citing an injury and was replaced by Felipe Arantes. Then, on August 7, Sicilia also pulled out and was replaced by promotional newcomer Kevin Souza, the former Jungle Fight featherweight champion. Kenny Robertson was expected to face João Zeferino at this event. However, Robertson pulled out of the bout citing an injury and was replaced by UFC promotional newcomer Elias Silvério, the former Jungle Fight welterweight champion.
