Former world champion Amir Khan has announced his retirement from the sport after a 17-year professional career.

The Briton, 35, is a former unified light-welterweight world champion and won silver at the 2004 Athens Olympics.

His final bout was a sixth-round knockout loss against rival Kell Brook – who also retired last week.

“It’s time to hang up my gloves,” Khan posted on social media. “I feel blessed to have had such an amazing career that has spanned over 27 years.”

Khan finishes his career with 34 professional wins and six losses, having turned professional in 2005.

“I want to say a heartfelt thanks to the incredible teams I have worked with and to my family, friends and fans for the love and support they have shown me,” he added.

From Olympic silver to world-title glory

Khan burst on to the scene as a 17-year-old at the 2004 Olympics. He was the only boxing representative for Team GB at the Games.
