Heavyweight boxer Audley Harrison has confirmed that he will hang up his gloves following a 12-year professional career in the sport.
"There are only so many times you can fall before it becomes foolhardy to continue," Harrison said on his official website. "I've fallen a lot, but winning the heavyweight title was a destination I really wanted to get to.
"Coming back from adversity has been synonymous with my life. I've done well to turn my life around, but sadly my dream to be a legitimate world champion will be unrealised.
"I believed if I was mentally and physically right, I could figure these young guns out. Saturday was my final chance to prove it. The thing that pulled me up was pride, so I wanted a chance to continue and go out on my shield. It was not to be."
Harrison, who won a gold medal in the Olympic Games in Sydney 2000, became the fist boxer to win the Prizefighter tournament for a second time in February this year.
