LONDON — Former heavyweight champion David Haye has announced his retirement, fulfilling his promise to quit by the time he reached the age of 31.
The British fighter’s last bout was a loss on points in July to Wladimir Klitschko, who added Haye’s WBA title to his own WBO and IBF belts.
Starting off as a cruiserweight before moving up to heavyweight, Haye — who turned 31 on Thursday — won 25 of his 27 fights as a professional.
He beat Russia’s Nikolay Valuev in November 2009 to capture the WBA title, successfully defending it against John Ruiz and Audley Harrison.
