Calvin Borel, the most well-known jockey in horse racing today, saddled up across Javier Castellano. In a particularly aggressive maneuver, Castellano cut his horse, Prince Will I Am, across the path of the other horses.
It actually looks like after Borel got in Castellano's face, it was Castellano who threw the first punch. This is the first jockey fight I can remember seeing; from the comfort of my desk, I think it's kind of a pity that they didn't attempt to fight while still mounted. Road Rash on horseback is one video game I would love to play.
