Haye announces retirement from boxing on his Birthday

According to the AP today.
October 13, 2011 — LONDON (AP) — Former heavyweight champion David Haye has announced his retirement on his birthday Thursday, fulfilling his promise to quit by the time he reached 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 won 25 of his 27 fights as a professional.
