The year of 2016 became one of the most eventful and memorable years in the history of the Ultimate Fighting Championship. The first UFC event in New York City and the rise of numerous notables made this year something special, but the year also shared its unfortunate moments. A significant damper fell in part due to the numerous UFC fight changes and cancellations in 2016. Below is a complete list of UFC fights that were originally scheduled to occur during the year but would be changed or cancelled due to: contract dispute, doping violation, fighter missing weight, illness, staph infection, injury, medical issue, personal issue, opponent rescheduling to fight someone else, rescheduling for a different event, retirement of an opponent, visa issue, and someone passing away.
