In FIBA the Captain takes over the role of Coach when there is no HC or AC available.

That said however, High school policy is there must be an adult on the bench supervising the students. So the game is forfeited if no coaches/school reps. are available.

Received this response from state CIF office when I posed that question two years ago:

There is a CIF rule,

308. SUPERVISION REQUIREMENT

No CIF team shall participate in interscholastic or approved competition with any other team unless the CIF team is under

supervision as required by the California Code of Regulations Title V or Bylaw 506.B.

Of course that would mean in any sport the coach must be present for the competition. In basketball that would mean that a coach must be on the bench. If a coach is ejected and there is not assistance coach and no administrator present, the game should be ended and forfeited to the other team.
