The 11-race program at Cal Expo was canceled on Friday due to unsafe riding conditions for the jockeys. Chad Schvaneveldt, assuming the leadership role as the jockeys' representative, held two meetings with the jockeys prior to the cancellation. Racetrack maintenance personnel worked feverishly to prepare the racetrack after the first three races were canceled. After an hour, the jockeys decided not to ride the rest of the program and Cal Expo officials abandoned the card. "We respect the jockeys' decision not to ride. We would never put horse or rider in any dangerous situation," director of racing David Elliott said. Racing will resume at the California State Fair on Saturday with a post time of 1 p.m.
