UFC 197: Jones vs. Saint Preux was a mixed martial arts event held on April 23, 2016, at MGM Grand Garden Arena in Las Vegas, Nevada.

[2] The event's number was initially planned for an event taking place on March 5, 2016 at HSBC Arena in Rio de Janeiro, Brazil,[3] before being cancelled on December 29, 2015[4] and moved to MGM Grand Garden Arena in Las Vegas, Nevada, to take place on February 6, 2016; the February event became UFC Fight Night: Hendricks vs. Thompson rather than a numbered pay-per-view after Vitor Belfort declined to fight Anderson Silva,[5] and the March show was renumbered as UFC 196.

The arrest took place five days after Jones was cited on multiple traffic charges, including drag racing, exhibition driving, weaving, failing to properly display his license plate and modifying his exhaust pipe.

[15] A UFC Flyweight Championship bout between current champion Demetrious Johnson and 2008 Olympic gold medalist in freestyle wrestling Henry Cejudo co-headlined the event.

[19] Former WSOF Women's Strawweight Champion Jessica Aguilar was expected to face Juliana Lima at the event, but pulled out on March 18 due to a knee injury.
