Rule 77 – Allocation of vacant Traps
Where there are fewer runners than the specified number for any Race that is not part of an eliminating round, the Racing Manager shall decide which trap(s) shall be left vacant; except that if the depletion of runners is due to the provision of Rule 91, or a Greyhound being withdrawn, the Trap Number(s) to be left vacant from those which would have been used shall be decided by the inclusion of the appropriate number of blanks in the draw corresponding to the classification of the disqualified or withdrawn runner(s).
