(a) The racing secretary shall close entries at the advertised time and may not accept any entries after that time. The racing secretary may postpone the closing of overnight races.
(b) After entries are closed, an entry may not be altered, other than to correct an error.
(c) If the number of entries exceeds the number of horses that may start in a race, due to track limitations, the racing secretary may split the race and the starters will be determined by lot.
(d) If a race is canceled because of insufficient entries, the racing secretary may split any overnight race or write a substitute race in place of the canceled race. Where an overnight race is split, forming two or more separate races, the racing secretary shall give notice of not less than 15 minutes before such races are closed to grant time for making additional entries to such split races.
(e) The owner or trainer of a horse that has been entered in a race who does not wish the horse to participate in the race must withdraw the horse from the race before entries are closed.
