Jon Jones again became the best fighter of the strongest league in the world two years and four months after he was stripped of this title by Khabib Nurmagomedov, who led the pound-for-pound rating after an early victory over Justin Gaethje.
Last weekend at UFC 285 in Las Vegas, 35-year-old Jon Jones successfully resumed his career after a three-year hiatus and won the vacant UFC heavyweight championship belt, finishing Frenchman Cyril Gan in the first round with a guillotine choke.
The American fighter will make his first title defense against his compatriot Stipe Miocic, whom he will meet on July 8 at UFC 290 in Las Vegas.
