"I gave this sport everything I had. I faced the best, moved through weight classes, and made history on my own terms. 42-0. 3x Undisputed. 5 Division World Champion. No shortcuts. No excuses.
"This isn't goodbye to boxing ... it's a thank you. Thank you to my family, my team, my city, and the fans who rode with me through every chapter. Thank you to the sport for shaping the man I am today. The gloves may have come off, but legacy is forever."
The 38-year-old Crawford finishes his career with a 42-0 record (31 KOs), including his last fight in September, anunanimous decision victory over Canelo Alvarez, taking the World Boxing Council super-middleweight title.
