Australia's Olympic champion hurdler Sally Pearson has confirmed earlier reports she tore a hamstring in training and won't compete at the Rio Games.
Pearson told reporters she still could've taken the start at Rio but would've been under prepared.
“I could go to the Olympics if I wanted to and come out of the blocks and jog to the first hurdle. That’s not what I’m about. I’m a competitor. This is my job and livelihood. For me it’s all or nothing. I can’t give my all and I won’t be for a little while now.”
The reigning Olympic 100m hurdles champion, suffered the injury while training on the Gold Coast last weekend, Australian news outlets reported on Wednesday.
Pearson said she would not say no if asked by Athletics Australia to attend the games as a mentor.
The 29-year-old has also not ruled out competing in future.
"This is what I do, as a job, this is who I am. I'm not just going to give up because I have an injury," Pearson said.
"This is a low time for me and it has been for a few years with different injuries, but I've always bounced back, I've always come back fitter, stronger and faster, and achieved amazing things still through adversity.
"I'm only 29, track and field athletes can go on for a bit longer. But at this stage I'm only looking forward to 2018 (Commonwealth Games on the Gold Coast).
"There's not many chances you get to run in a major championships 10 minutes up the road from your house. It will be pretty special."
Pearson, the reigning Olympic 100m hurdles champion, would be 31 for the Commonwealth Games and 34 by the time of the Toyko Olympics.
She returned to Australia in a bid to find form and fitness after three sub-standard races in Europe.
The races were Pearson's comeback from a broken wrist and a torn calf muscle sustained in fall in a race in June last year.
