Former UFC light heavyweight champion Jon Jones will attempt to regain his belt when he returns from suspension Dec. 29 in a rematch with Alex Gustafsson.
The UFC announced the main event for its traditional year-ending show in Las Vegas on Friday.
Jones (22-1) is widely considered the greatest talent in mixed martial arts, but he has repeatedly sabotaged his own career with mistakes outside the cage.
Jones hasn't fought since July 29, 2017, when he beat Daniel Cormier to win the light heavyweight title for the second time. Jones' victory was overturned when he tested positive for steroid use and received a 15-month suspension.
Jones beat Gustafsson in their first bout in September 2013, escaping with a debatable decision in the toughest fight of his professional career.
