Vlasic ruled out of Games

The 28-year-old - who took silver in the 2008 Games in Beijing - had been struggling to be fit for London after undergoing surgery on her left foot in April - two months after she had undergone surgery on an Achilles tendon.

But she caught a bacteria that caused an infection putting into question her further recovery and competition at the Games which start on July 27 and on Saturday she admitted she had lost her battle.

"I"ve been postponing decision about my participation in London hopeful to get some positive wind into my back," said the 2007 and 2009 outdoor world champion on her blog.

"But time is running out and time is the only thing that I need right now.

"In this moment my health situation is getting better and my trainings are more complex every day.

"Still, I will not be able to get into the top shape in time for Olympic Games. I"m not interested in jumping below my usual level, so It is the best thing to stay home and get the healing process to the end.

"I feel this is only a minor set back in my career and I"m looking forward to many more years of successful jumping. This is my chance for a new beginning!"
