Under the new rule, a layoff report must be submitted prior to entry in a race for a horse that has not raced in 150 days or more. HISA recommends that the reports be uploaded to the HISA portal 10-14 days prior to the entry day. Trainers will be notified through HISA when a horse has been away from racing for 140 days.
More information on how to submit a report is available at this link, which provides a PDF step-by-step explanation: https://hisa-
