Things got very interesting even before the Kentucky Derby got underway when one of the horses reared up and threw his jockey as he was being loaded into the starting gate.As the starting gate was being loaded up, Great White, ridden by jockey Alex Achard, appeared to get spooked by something, reared up, and fell backwards.That sent Achard tumbling, with the 1,300-pound horse landing on his back and almost rolling on top of the jockey.CLICK HERE FOR MORE OUTKICK SPORTS COVERAGEFortunately, both Achard and Great White appeared to be OK after the incident, though the horse was immediately scratched and led away from the gate. The rest of the field was then loaded, and the race went off without incident.Golden Tempo, who entered the race at 30-1, came away with the win.Man, what a heart-in-mouth moment that was before the race even began.For some reason, I think we forget just how big horses are because they're usually pretty cool. But now and then one decides, "Meh, I'm not doing this whole racing thing today," and rage-quits, just not always like that.ZERO BS. JUST DAKICH. TAKE THE DONT @ ME PODCAST ON THE ROAD.
