UFC 196
UFC 196: McGregor vs. Diaz was a mixed martial arts event held on March 5, 2016 at MGM Grand Garden Arena in Las Vegas, Nevada. Background. The event was officially announced in November 2015 as "UFC 197," taking place on March 5, 2016 at HSBC Arena in Rio de Janeiro, Brazil. Weeks later on December 29, UFC announced that the event was canceled and would be moved to a different location. On January 12, it was confirmed the event would take place at the MGM Grand Garden Arena in Las Vegas, Nevada. On January 13, UFC revealed this  event was originally intended to take place at Arena da Baixada (a much larger venue) in Curitiba, Brazil, and feature a UFC Heavyweight Championship rematch between champion Fabrício Werdum and former two-time champion Cain Velasquez, with former UFC Middleweight Champion Anderson Silva in the co-main event slot, possibly against Michael Bisping. Due to a series of injuries, the company moved the heavyweight bout to a separate event scheduled for February 6, which at that time was . This change made the March 5 event a smaller draw, which led to the transition to the smaller venue in Rio de  Janeiro. To maintain local interest, the company then considered booking the main event as a rematch between two Brazilian fighters, Silva and former UFC Light Heavyweight Champion Vitor Belfort. Belfort declined the bout, as he wished to wait for the result of the middleweight title fight at UFC 194. This final fall-through is what prompted the cancellation of the event in Brazil and relocation to Las Vegas. On January 27, it was revealed the Werdum-Velasquez bout (which had been moved to "UFC 196" scheduled for February 6, 2016) was cancelled entirely. This forced that event to alter into  a "UFC Fight Night" card, and the originally scheduled "UFC 197" event was renamed UFC 196. The event was expected to be headlined by a UFC Lightweight Championship bout between champion Rafael dos Anjos and UFC Featherweight Champion Conor McGregor. This would have been the second time in UFC history that champions in different divisions would fight for the same title. The first time was at UFC 94 on January 31, 2009, when then-UFC Welterweight Champion Georges St-Pierre defended his title against then-lightweight champion B.J. Penn. On February 23, the planned bout suffered a setback as it  was announced that dos Anjos pulled out due to a broken foot. Former UFC Featherweight Champion José Aldo declined the initial opportunity to replace him due to "lack of time" to prepare for the bout. Former lightweight champion and top featherweight contender Frankie Edgar also declined the opportunity due to a groin injury. Eventually, The Ultimate Fighter 5 winner and former lightweight title challenger Nate Diaz was announced as the replacement and the bout took place in the welterweight division. A UFC Women's Bantamweight Championship bout between then champion Holly Holm and former Strikeforce Women's Bantamweight Champion Miesha  Tate co-headlined the event. Michael Johnson was expected to face Tony Ferguson in a lightweight rematch. On January 27, it was announced that Johnson withdrew from the bout due to injury. Ferguson was then rescheduled to fight at on April 16 against Khabib Nurmagomedov. A welterweight bout between Brandon Thatch and Siyar Bahadurzada, originally slated for , was rescheduled to this event due to Thatch's medication being banned by Pennsylvania's athletic commission.
