Cat Manzi and Eric Goodell were injured in a crash in the 12th race, which began when Goodell's horse, Fake Denario N, tumbled to the track. Three other horses and their drivers were involved in the accident. The 13th race was canceled.

Mike Tanner, the track's director of racing operations, said the drivers were placed on backboards and taken by ambulances to Crozer-Chester Medical Center for evaluation. He said both drivers were conscious on the track when they were transported. Tanner declined further comment as he awaited word from the hospital.

Brian Sears and Tim Tetrick also were involved in the accident but walked away, apparently unhurt. None of the horses appeared to be injured seriously.

"I can't describe it," said Bob Rudolph of Vineland, N.J., who shares ownership of the horse with the Lindy Racing Stable and Gary and Ellen Hoffman. "I never would have dreamed this."
