Overshadowing the performance of Big Brown in the Kentucky Derby was the fact a horse had to be euthanized on the track after the race.

Eight Belles suddenly collapsed after the race, and it was later found out to be broken ankles on two legs, giving doctors little choice on the course of action.

The strangest part about the injury was that it did not occur until a couple of minutes after the end of the race.

After the death of Barbaro a couple of years ago, horse racing has been dealing with an image issue because of injuries suffered by the animals during competition.
