The event was headlined by a UFC Lightweight Championship bout between the undefeated current champion Khabib Nurmagomedov and former featherweight and lightweight champion Conor McGregor. McGregor captured the lightweight title at UFC 205, when he was the reigning featherweight champion. McGregor never defended the title, he took some time off in 2017 due to the birth of his first son and later venturing himself in a boxing match against Floyd Mayweather Jr.. The UFC originally planned an interim title bout between Nurmagomedov and welterweight winner Tony Ferguson, but it was canceled due to Khabib having medical issues related to his weight cut on weigh-in day. Ferguson eventually won the interim title at UFC 216 against Kevin Lee. Ferguson was then expected to meet Nurmagomedov at UFC 223, with the winner being crowned the undisputed champion. In turn, it was scrapped once again as Ferguson got injured, and after several possibilities for an opponent, Nurmagomedov eventually won the vacant title against Al Iaquinta. That card was also marked by an attack on a bus containing several fighters scheduled to compete at the event, performed by McGregor and his crew. Jussier Formiga was previously scheduled to face Sergio Pettis in January 2017 at. However, Formiga pulled out of the fight for undisclosed reasons. The pairing was rescheduled for this event. On October 1, Sean O'Malley announced that he was pulled from a bout against José Alberto Quiñónez after failing a US Anti-Doping Agency drug test. In turn, promotion officials elected to remove Quiñónez from the card and he will be rescheduled for a future event.

Nurmagomedov-McGregor post-fight controversy
Seconds after the fight, Nurmagomedov climbed out of the octagon and charged toward McGregor's cornerman Dillon Danis. Soon after, McGregor and Abubakar Nurmagomedov also tried to climb out of the octagon, but a scuffle broke out between them. Back in the octagon, McGregor was then attacked by two of Nurmagomedov's cornermen: Zubaira Tukhugov and Esed Emiragaev. As a result of the incident, Nurmagomedov's payment for the fight was withheld by the Nevada State Athletic Commission pending an investigation into his actions. Tukhugov was scheduled to fight on October 27 at against Artem Lobov, McGregor's teammate who was confronted by Nurmagomedov in April 2018. Nurmagomedov appeared at the post-fight interview and apologized to the NSAC, saying he was provoked by the McGregor team's trash-talk targeting his family, nation, and religion, as well as the UFC 223 bus incident. Nurmagomedov later told Russian media that he was triggered by a number of insults he heard from Danis during the match, including anti-Muslim slurs. The NSAC filed a formal complaint against both McGregor and Nurmagomedov and the final hearing was initially scheduled to take place in November. On October 12, they announced both fighters received a suspension for ten days come October 15 and a hearing would be held on October 24. On October 24, the NSAC unanimously voted to release half of Nurmagomedov's payout immediately. The commission also voted to issue temporary suspensions for both fighters and ordered them to appear in person for a further hearing in December to resolve the case. On January 29, 2019, the NSAC announced a nine month suspension for Nurmagomedov and a $500,000 fine. The agreement also includes a potential suspension reduction of up to three months if he delivers to the commission a public service announcement on anti-bullying. To receive the reduction, the commission must approve the PSA and its distribution plan. Additionally, Nurmagomedov can only receive credit based on the time he submits the PSA. McGregor was suspended for six months and given a $50,000 fine. In separate agreements, Abubakar Nurmagomedov and Tukhugov were each suspended one year for their roles in the melee. All suspensions are retroactive to the day of the event. A few days later, Nurmagomedov stated that he would not opt to do the PSA stating “The state of Nevada is where drugs, prostitution and gambling are officially permitted. Let them work on themselves.” Danis was suspended for seven months and fined $7,500, also retroactive to the day of the event. On May 22, 2019, NSAC reduced the suspensions by 35 days which allowed Abubakar Nurmagomedov and Tukhugov to be eligible to compete again on September 1, 2019.
