It has been a year and a half since the undisputed Ultimate Fighting Championship light heavyweight title has been up for grabs. After Daniel Cormier defeated Anthony Johnson in May 2015 and captured the championship vacated by Jon Jones, the belt has been defended once and interrupted several times. Jones came back to win an interim title against Ovince St. Preux a year ago but was forced out of a unification bout with Cormier at UFC 200 after a last-second United States Anti-Doping Agency violation. Then, the rematch between Cormier and Johnson was scheduled for UFC 206 in December, only to be scrapped by an injury to the champion.
