For months, light heavyweight champion Joe Calzaghe has been saying he would probably retire. On Thursday, he did. Perhaps the greatest fighter in Welsh history, Calzaghe, a two-division world champion and one of the best fighters pound-for-pound in the world, announced his retirement from boxing, saying he had nothing left to accomplish. "It was a difficult decision but I have achieved everything I wanted to achieve in boxing. I've been world champion for 11 years. I've got no other goals to go for. That's why I am calling it a day," Calzaghe, 36, told BBC. "I had a long think with my family. My children wanted me to give up, plus my mum. That's why I called it a day and will go on to do something else. My decision is to retire. I've been boxing for 25 years and, like I said, I've achieved everything I want to achieve."
