UFC 232: Jones vs. Gustafsson 2 was a mixed martial arts event produced by the Ultimate Fighting Championship that was held on December 29, 2018 at The Forum in Inglewood, California.

[2][3] A UFC Light Heavyweight Championship bout between former champion Jon Jones and former title challenger Alexander Gustafsson headlined this event.

[5] The rematch was previously booked to headline UFC 178 in September of 2014, but the pairing was scrapped after Gustafsson tore his right meniscus and lateral collateral ligament.

[8] The event was originally expected to take place at T-Mobile Arena in Paradise, Nevada, part of the Las Vegas Metropolitan Area.

However on December 23, the event was moved to The Forum in Inglewood, California due to a Jones' drug testing abnormality stemming from earlier that month.

[22] On February 28, Harris was suspended for four months (retroactive to the day of the fight) and fined $4,000 by the CSAC for the failed drug test, as he was able prove that he ingested the substance via a tainted supplement.
