From what I have read, it did happen after the end of the race when she was being pulled up. I have read reports this morning, though I don't know if they are true or not, that the track requests(ed) that the jockeys pull up early because they want to get to the ceremony (to save time on TV) rather than let them run them out another 3/4 mile or so. If you were watching, you could see even Big Brown was so fresh after being pulled up at the finish that he dumped his jockey. If this is true, so much the sadder (and shameful).
