UFC 214: Cormier vs. Jones 2 was a mixed martial arts event produced by the Ultimate Fighting Championship and held on July 29, 2017, at the Honda Center in Anaheim, California.

[4] Subsequent to that victory, Jones was stripped of the title and suspended indefinitely from the UFC in connection with a hit-and-run incident in which he was involved.

[6] 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.

However, Jones was pulled out of the fight by USADA due to a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection on June 16.

[16][17] In turn, Anderson pulled out on June 27 for personal reasons and was replaced by current Invicta FC Bantamweight Champion Tonya Evinger.

[32] Reports began to circulate on June 28 that Cerrone had sustained a minor injury and that the pairing would be left intact, but shifted to this event.

[33] UFC President Dana White confirmed later that Cerrone in fact had a staph infection and a pulled groin, and while the plan was to keep the bout, it wouldn't happen at this event.

[36] Sara McMann and Ketlen Vieira were expected to face each other at the event, but on July 7 it was announced that the bout was moved to UFC 215 in September.

[37] A heavyweight fight between Dmitrii Smolyakov and promotional newcomer Adam Wieczorek was scheduled for the preliminary portion of the event.

[42] On August 22, it was announced that Jones was flagged for a potential doping violation by USADA stemming from his urine test sample collected after fight weigh-ins on July 28.

Jones was placed on a provisional suspension as a result of the positive drug test pending the full adjudication process.

The independent arbitrator, well-known anti-doping investigator Richard McLaren, found Jones had "some degree of fault" for the steroid metabolite that showed up in his system, but "the violation was not intended nor could it have enhanced" his performance.
