The 38-year-old from Nebraska, who dominated Mexican legend Alvarez in Las Vegas in September to claim the undisputed super middleweight crown, announced his decision in a video posted on social media.

"I'm stepping away from competition, not because I'm done fighting, but because I've won a different type of battle," Crawford said in his retirement message. "The one where you walk away on your own terms."
