(a) In addition to any other valid ground or reason, a horse is ineligible to start in any race:

(1) if such horse is not registered by the Jockey Club if a thoroughbred, the United States Trotting Association if a standardbred, the American Quarter Horse Association if a quarter horse, the Appaloosa Horse Club if an appaloosa horse, the Arabian Horse Registry of America if an Arabian horse, or the American Paint Horse Association if a paint horse;

(2) if the parentage verification to both the sire and the dam of all horses foaled in 1992 and thereafter has not been certified by the Jockey Club if a thoroughbred, the United States Trotting Association if a standardbred, the American Quarter Horse Association if a quarter horse, the Appaloosa Horse Club if an appaloosa horse, the Arabian Horse Registry of America if an Arabian horse, or the American Paint Horse Association if a paint horse;

(3) if, unless the stewards permit otherwise, the certificate of foal registration, eligibility papers, or other registration issued by the official registry for such horse is not on file with the racing secretary at the time of entry;

(4) if such horse has been entered or raced at any recognized race meeting under any name or designation other than the name or designation duly assigned by and registered with the official registry;

(5) if the certificate of foal registration, eligibility papers or other registration issued by the official registry has been altered, erased, or forged;

(6) if the identification markings of the horse do not agree with the identification markings as set forth in the registration of such horse;

(7) unless he is eligible to enter said race and is duly entered for such race;

(8) when such horse is owned in whole or in part by an unlicensed person or is in the care of an unlicensed trainer;

(9) when such horse is on the Steward's List, the Starter's List or the Veterinarian's List;

(10) when, except with prior approval of the stewards for good cause, such horse is on the Veterinarian's List in another racing jurisdiction. Good cause includes:

(A) unforeseen administrative issues in removing the horse from the Veterinarian's List of another racing jurisdiction;

(B) the location of the horse prevents it from being evaluated by the official veterinarian of another racing jurisdiction and cleared from that jurisdiction's Veterinarian's List, and the horse is approved to race by a California official veterinarian; or

(C) any other unforeseen event or reason that would prevent a horse that would otherwise not be on a Veterinarian's List from being cleared from the Veterinarian's List of another racing jurisdiction.

(11) when, except with prior approval of the stewards, such horse has not been on the grounds of the association or its approved auxiliary stable area for at least 24 hours prior to the time the race is to be run.

(12) when such horse does not carry a microchip or has not received a waiver from the stewards in accordance with Rule 1597.5.

(13) when such horse has received an intra-articular injection within the previous fourteen days prior to the scheduled post-time for the race in which it is entered.

(14) when such horse has not raced at a recognized race meeting within 12 consecutive months since its previous start, until the horse has performed satisfactorily in a workout or standardbred qualifying race as provided in Rule 1866(h) and (i).

(15) when such horse is a first-time starter four (4) years of age or older, until the horse has performed satisfactorily in a workout or standardbred qualifying race as provided in Rule 1866(h) and (i).
