I was watching on TV. The horses had already come on the track for the 9th race and were scoring down. The next thing I know, the camera feed stopped showing the track feed and posted a sign "they'll be a delay before the 9th race". Corey must have gotten hurt somehow and the ambulance probably took him to the hospital and they couldn't start the race until another ambulance came to replace it. Haven't heard or read anything about what happened.
