British boxer Audley Harrison has announced his retirement from the sport following his fourth career defeat at the weekend.
The former Olympic super-heavyweight champion was knocked down and counted out within 70 seconds against Deontay Wilder in Sheffield on Saturday night.
Harrison today confirmed on his personal website it will be his last action in the ring in a statement titled "I'm retiring".
"There are only so many times you can fall before it becomes foolhardy to continue," he wrote. "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."
Harrison added: "I’ve done well to turn my life around, but sadly my dream to be a legitimate world champion will be unrealised."
