Like I'm sure you guys know, a horse had never been DQ'ed for an in-race infraction before yesterday. It appears the stewards were content to let the results stand but were forced to address the incident when the jockeys claimed foul. If this was just another mid-week race, it wouldn't have taken 20 minutes to DQ the horse, it would have taken 2. It must have been agony for the stewards, they didn't want to do it but they had to.
But I was surprised to read that there hadn't been a foul claim since 2001. I wonder if there was an unwritten rule violated here.
