Jon Jones suffered an injury this week that has forced the postponement of his next title defense.
Jones had been slated to defend his belt against Daniel Cormier in the UFC 178 main event on Sept. 27 in Las Vegas. Jones, however, suffered a leg injury in training that has forced him out of the bout.
The UFC announced the postponement during Tuesday’s edition of America’s Pregame on Fox Sports 1.
The fight will now take place at UFC 182 on Jan. 3, 2015.
With the fight postponed, UFC flyweight champion Demetrious Johnson steps into the UFC 178 main event slot.
Johnson was supposed to put his belt on the line against Chris Cariaso in the UFC 177 co-main event on Aug. 30 in Sacramento, Calif. He will still defend against Cariaso, but the bout will headline UFC 178.
There has still been no word from the Nevada Athletic Commission or UFC officials about what or if any penalties Jones and Cormier will suffer for their respective roles in a skirmish during a UFC media day event on Aug. 4 in Las Vegas.
