Two Jockeys Fight at The Breeder's Cup

Louisianan Calvin Borel, the most well-known jockey in horse racing today, raced today in Louisville in a key race against fellow jockey, Javier Castellano. In a particularly aggressive maneuver, Castellano cut his horse, Prince Will I Am, across the path of the other horses.

Borel, who has won three of the last four Kentucky Derbies, took exception. And then all hell broke loose.

It looks to me like it was Castellano who threw the first punch.  Reports also say that they went at it again in the lockerroom.
