It's wait until next year for sprinter Marion Jones.
Back spasms will prevent Jones from competing again this year, but she still plans to seek an unprecedented five gold medals at the Sydney Olympics.
She still hopes to win gold in the 100 and 200 meters, long jump and 400 and 1,600 relays next year, her agent, Charlie Wells, said.
Jones collapsed on the track in the semifinals of the women's 200 meters at the world championships last week in Seville, Spain, suffering from cramps and back spasms.
She returned to the United States over the weekend for further evaluation.
