(d) Qualifying races. Declarations for overnight events shall be governed by the following:
(e) Entries.
(g) Preference. Preference shall be given in all overnight events according to a horse's last previous purse race during the current year. The preference date on a horse that has drawn to race and then scratched is the date of the race from which he was scratched.
(h) Steward's list. A horse may be placed on the "steward's list" if:
(k) Eligibility certificate posted by clerk of the course concerning horse on "steward's list". The clerk of the course shall make a note on the eligibility certificate of such horse showing the date the horse was placed on the "steward's list", the reason therefor, and the date of removal if the horse has been removed. If a horse is placed on the "steward's list" due to sickness or lameness, he shall only be removed from the list by the association veterinarian.

Drivers may be changed until designated scratch time, but the presiding judge must be notified thereof.
