Undefeated Calzaghe hangs up his gloves

UNDEFEATED world super- middleweight and light-heavyweight champion Joe Calzaghe has announced his retirement from boxing.

The 36-year-old Welshman, who outpointed Roy Jones Jnr in his last fight in November, confirmed he was hanging up his gloves after winning all of his 46 professional bouts.

“It was a difficult decision but I have achieved everything I wanted to achieve in boxing,” he said.
