American sprinter Marion Jones has pulled out of the most prestigious grand prix meeting in the US, after two poor performances in Europe.
The former triple Olympic champion's name was not on a list of women's 100 metres contestants released on Thursday for Saturday's Prefontaine Classic.
The meeting is heavily endorsed by Jones's major sponsor Nike and has attracted 16 Athens Olympic gold medallists and a bevy of top international athletes including British world marathon record holder Paula Radcliffe.
Organisers had never announced Jones's entry, but the former sprint queen had told a news conference on Tuesday in Milan that she would run a 100-metres in Oregon.
She apparently changed her mind after being beaten for the second time in four days by former training partner Chandra Sturrup in Milan yesterday.
