Chael Sonnen stepped in as a late replacement for Olympic wrestling champion Gable Steveson, who withdrew due to a toe injury sustained during training. The 48-year-old former middleweight and light heavyweight title contender faced Jones in what was scheduled as a three-round, five-minute per round superfight.
