When Col John (my key) hung in the lane I focused on Eight Belles and thought, as you did, that she suddenly wavered about the 16th pole. At the time I thought the horse was merely tiring, but it could have been the injury.
One note, and I\'ve commented on this over the years, condylar issues (and this was a condylar fracture) don\'t happen without warning. They are the final stage of a steady bone deterioration, which goes on for months.
Generally, horses become \'ouchy\' and are given a variety of pain killers to enable them to keep training. Occasionally they are taken out of training and can recuperate, given enough time. Tale of the Cat was such a horse.
I don\'t know if the connections knew whether the filly was having this problem, but even if they did, the stakes were tremendous for a 3yo (and they are only 3 once.)
