Bottom line: Jon “Bones” Jones got his nickname from his high school football coach because he was so skinny. By the time he rose to UFC dominance, he was a lethal 6-foot-4 and 205 pounds.
Jones became the youngest champion in UFC history when he won the light heavyweight title in 2011, at 23 years old. He held the title from 2011 to 2015 and again from 2018 to 2020, with 10 title-defending fights to go with nine wins over former UFC champions in different categories.
While Jones is the greatest UFC fighter of all time, he’s also been one of the most controversial figures in professional sports over the last decade because of a string of arrests for domestic violence, battery, hit-and-run and DUI, along with multiple suspensions for failing drug tests ahead of fights.
