I don't know how accurate the Huffington post is but this is their article:

"Eight Belles actually ended up finishing second in the race, just behind Big Brown. But in a shocking and tragic development, just as Eight Belles crossed the finish line, jockey Gabriel Saez "heard the worst sound possible - a pop."
Saez said the filly did not take a bad step, but he heard the pop and tried to pull her up.
"I tried to get her to stop," he said. "I tried to get her to stop, but she wouldn't stop." "
This is the only source I can find that states what Saez supposedly heard during the race.
Either way, I cannot see blaming the jockey. If what is above is the truth it fits Eight Belles to a "T". Jones repeatedly made mention that this filly was very hard to pull up, even after a long gallop.
I would hazard a guess against better judgement, and say maybe the adrenaline just ran out..we saw last year Indian Flare make it all the way back to be unsaddled only to drop dead of a pelvic fracture. Who knows? Out of all the people to pick on in this event, they choose a young jock who went down with his horse and accuse him of whipping her till the point of endangering his own life.
