Andre Phillips, the world's No. 1 ranked 400-meter intermediate hurdler the last two years, won't be able to run in the USA-Mobil outdoor track and field meet that starts today with decathlon and heptathlon competition at San Jose City College.
Phillips is suffering from a stress fracture in his right shin that has prevented him from training.
The meet in San Jose qualifies athletes for the World Championships Aug. 29-Sept. 6 in Rome.
"It's important that I am in good physical shape next year for the Olympic Games," Phillips said. "I plan to run in Europe in August and my goal is to break the world record."
Edwin Moses is the world record-holder at 47.02 seconds.
