BROOKLYN, Mich. (AP) _ Flying debris from a crash at the U.S. 500 on Sunday injured seven spectators, three of them critically.

Driver Adrian Fernandez crashed more than halfway through the CART race at Michigan Speedway, sending his car's right front tire and parts of its suspension into the crowd.

Track spokesman Tommy Cameron said the most seriously injured spectators were taken by helicopter to a hospital in Jackson. The others were treated at the infield medical center.

Fernandez, the pole winner, came away from the crash with bruised knees. The Mexican driver was third at the time. His car slid into the wall on lap 175 of the 250-lap race on the 2-mile, high-banked oval.
