Arizona Tribune - Undefeated boxing great Crawford announces retirement

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."

Crawford, (42-0, 31 knockouts), retires as the reigning WBA, IBF and WBO supermiddleweight champion after defeating Alvarez by unanimous decision in a masterful performance.

Crawford had also held the WBC super middleweight belt, but was stripped of it earlier this month following a dispute over sanctioning fees.

Speaking in his video, Crawford said his career had been driven by a desire to keep "proving everyone wrong."

"Every fighter knows this moment will come, we just never know when," Crawford said.

"I spent my whole life chasing something. Not belts, not money, not headlines. But that feeling, the one you get when the world doubts you but you keep showing up and you keep proving everyone wrong."

"I fought for my family. I fought for my city. I fought for the kid I used to be, the one who had nothing but a dream and a pair of gloves. And I did it all my way. I gave this sport every breath I had."

Crawford's career straddled three different decades, with the southpaw making his professional debut in 2008 and rapidly becoming one of boxing's brightest talents.

He won his maiden world title, the WBO lightweight crown, with victory over Scotland's Ricky Burns in 2014.

Crawford won 18 world titles in five weight classes, culminating in his win over Alvarez.

He retires having never been officially knocked down in a fight.

All of his 42 victories have come by way of unanimous decision or stoppage, with no judge ever scoring in favour of an opponent during his career.
