Jones was to be the USA's 100m runner and part of their sprint relay team.

However, she has not raced since revelations surfaced in August that she had failed a drugs test in June.

Although her A sample tested positive for the blood-booster EPO, her B sample tested negative and last week she was cleared of doping.

But the 30-year-old triple Olympic champion is never far from suspicion and her excuse for missing the World Cup will undoubtedly set the rumour mill spinning all over again.

Just before the fourth Golden League meeting in Zurich in August, Jones pulled out citing personal reasons but a leak later revealed it was because she had found out about her positive A sample from the US championships.
