CARSON, California (AP):

Sprinters Veronica Campbell-Brown and Tyson Gay pulled out of this week's Adidas Track Classic on Wednesday.

Campbell-Brown, who won the 200 metres at the Beijing Olympics for Jamaica, was due to make her outdoor season debut in the same event but pulled out because of a toe injury that has limited her since February.

Gay is the reigning world champion in the 100 and 200 metres. His management group, Global Athletics & Marketing, said that he was "just not ready to run a 100 or 200 yet."

"We're disappointed that he's not competing, but we had a hope that we could get him the opportunity to compete here," said Rich Kenah, the director of marketing. "The good news for Tyson is that in the last few weeks he's found out that he's actually in better shape than what he anticipated."

A knee injury cost Gay six weeks of training at the beginning of the year, but he made his first appea-rance since Beijing at the Texas Invitational meet on May 3, where he ran a 45.57 in the 400 metres. He is scheduled to face off against former world record-holder Asafa Powell at the Reebok Grand Prix on May 30.

The Classic, which takes place on Saturday, will feature Beijing Olympic medallists Allyson Felix, Jenn Stuczynski and Jeremy Wariner of the United States.

Felix will run the 200, while Wariner will compete in the 400, his signature event.
