[4] A middleweight bout between Brad Tavares and The Ultimate Fighter: Brazil 3 heavyweight winner Antônio Carlos Júnior was scheduled for the event.

However, Tavares was forced to pull out of the fight due to an anterior cruciate ligament (ACL) injury.

VanZant requested to reschedule the bout one month later, but Ribas decided to remain at the event and Randa Markos stepped in as the replacement.

However, due to the COVID-19 pandemic in mainland China, Mudaerji was forced to withdraw from the event as he would not travel to prepare for the fight and was replaced by promotional newcomer David Dvořák.

[10] On March 12, the UFC announced that this event would take place behind closed doors (for the first time in the promotion's history) after Ibaneis Rocha, the governor of the Federal District (where Brasília is located), announced that large gatherings will be suspended or closed for a period of 5 days due to the COVID-19 pandemic.
