The horses included in the section, "Mysterious Disappearances," include any horses that had an injury that occurred in one race or over the course of a few races. Four of these horses are now retired, with two remaining active in racing and one passing away after retirement. Typically these horses were not immediately known to have injured themselves considering they did not physically collapse on the track. Their racing careers have either ended or they have not raced in noteworthy races since their injuries. Descriptions of each horse are provided after their name, as well as a picture of the horse with a confomational analysis to discover the harmful qualities that could explain their mysterious injuries and disappearances from the track.
