Jon Jones is back, and it will be as if nothing changed. Jones, who was stripped of the UFC light heavyweight title on April 29, 2015, after being involved in a hit-and-run accident in Albuquerque, N.M., will challenge Daniel Cormier for his old belt when they meet for the title in the main event of UFC 197 on April 23 at the MGM Grand Garden. A flyweight title fight between champion Demetrious Johnson and No. 1 contender Henry Cejudo will be the co-main event.
