The boxer who won the super-heavyweight gold medal at the 2000 Sydney Olympics has retired from the sport, citing concern over brain injuries.
"After years of denial and sticking to my guns, I'm finally getting out of my own way," Audley Harrison of Britain said in a statement on his website. "As tough as it is to say this ... it's time to stop."
The 43-year-old former European heavyweight champion said he has suffered from problems with vision, balance and mood swings. He said tests have shown evidence of traumatic brain injury.
Now living in California, Harrison finishes his pro career with a 31-7 record.
