Sotherton retires after Olympics KO
Heptathlete Kelly Sotherton has called time on her career after failing to recover from injury in time for Olympics qualification.
Sotherton, who won heptathlon bronze at the 2004 Olympics in Athens, recently had an operation to remove a piece of disc in her back.
Medics said she would not be able to resume running for six weeks, meaning the 35-year-old will miss the GB Olympics selection deadline.
"I thanked the doctors but there's no chance. You have to know when to stop," Sotherton told the Mail on Sunday.
Sotherton has had problems with her back at various stages throughout her career. She discovered a fracture to her spine four months after clinching Commonwealth gold in Melbourne in 2006, before missing a large chunk of 2010.
She broke down in the 200m at the IAAF Combined Events Challenge in Italy earlier this month and immediately realised her London 2012 dream was over.
"As soon as it went I knew that was it. I could hardly walk and could hardly move. At that moment, I said 'It's over'," Sotherton added.
