UFC 200: Tate vs. Nunes was a mixed martial arts event produced by the Ultimate Fighting Championship held on July 9, 2016, at the T-Mobile Arena on the Las Vegas Strip in Paradise, Nevada. This event suffered a major hit only three days before it happened, as it was announced that Jones was pulled out by USADA due to a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection on June 16. Cormier declared he would still fight if an opponent brought to him "made sense". It was announced that former UFC Middleweight Champion Anderson Silva would replace Jones on less than two days' notice and face Cormier in a three-round non-title light heavyweight bout. Due to those major changes, the already scheduled UFC Women's Bantamweight Championship bout between then champion Miesha Tate and top contender Amanda Nunes was revealed as the new main event.

UFC Fight Night 78: Magny vs. Gastelum was a mixed martial arts event held on November 21, 2015, at the Arena Monterrey in Monterrey, Mexico. A welterweight bout between Neil Magny and Kelvin Gastelum served as the event headliner.
