OFFICIAL FAILS TO ARRIVE
In the event a contracted official fails to arrive for a scheduled contest,
those officials who are present may 1) officiate the contest with less than
the usual number of officials; 2) re place the absent official with a local
registered official to fill-in or 3) cooperate with the involved teams to post -
pone the contest.
Note: It is never an option to accept or use the services of an
unregistered official.

For an official ruling, give the state a call. They'd be more than happy to advise.
