context_page_description: 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.
  It was the final UFC event under the ownership of Frank and Lorenzo Fertitta, which began in January 2001. Zuffa subsequently announced its sale to a group led by WME-IMG, an American talent agency with offices in Beverly Hills, which included Silver Lake Partners, Kohlberg Kravis Roberts, and MSD Partners.
context_section_description: A welterweight rematch between The Ultimate Fighter 5 winner and former lightweight title challenger Nate Diaz and the then current UFC Featherweight Champion Conor McGregor was originally expected to headline the event. The pairing previously met earlier in the year at UFC 196. McGregor was expected to challenge UFC Lightweight Champion Rafael dos Anjos, but dos Anjos pulled out due to a broken foot only 11 days before the event. Diaz eventually replaced him and the bout was shifted to the welterweight division. Diaz won the fight via rear-naked choke in the second round.
  On April 19, after McGregor tweeted a supposed retirement, the UFC announced that he was pulled from the event and a replacement for him was being sought. UFC President Dana White clarified that McGregor's removal was related to his refusal to come to a press conference that week, because "he was in Iceland training and didn't want to ruin his preparation for the fight". McGregor released a statement two days later, claiming he was not retired and that he requested the UFC to allow him to focus more on the fight preparation this time, as he felt he lost his focus during the media obligations for the previous fight. He then stated that he was ready for the event and would come for a scheduled New York press conference, but if that's not enough, he "doesn't know what to say". A report later claimed that the UFC decided to cancel the fight indeed, in what was rumored to be a $10 million paycheck for McGregor.
  On April 27, the UFC officially announced the new headliner as a UFC Light Heavyweight Championship unification rematch between current champion Daniel Cormier and former champion Jon Jones, who is also the current interim champion. The pairing met previously at UFC 182 in January 2015 with Jones defending his title via unanimous decision. Subsequent to that victory, Jones was stripped of the title and suspended indefinitely from the UFC in connection with a hit-and-run incident that he was involved in. Cormier replaced him and went on to defeat Anthony Johnson at UFC 187 to win the vacant title. Their rematch was originally expected to take place at UFC 197, but Cormier pulled out three weeks before the event due to injury and was replaced by Ovince Saint Preux, in what became an interim title bout. Jones went on to defeat Saint Preux by unanimous decision and won the interim title.
  The event suffered another 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". Additional information on Jones' situation will be provided as the process moves forward. A day later Jones apologized for the incident, but denied knowingly taking any illegal substance. He and his manager also declined to specify the substance that resulted in the failed test. His "B" sample also came positive for the same substances and Jones' faces a potential two-year suspension.
  During the UFC Fight Night: dos Anjos vs. Alvarez broadcast, 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.
