The wiser course of action would be to suspend the game if a decision was reached to stop and let the governing body sort it out.
Personal safety is a GENERAL (and PRIMARY) concern regarding EVERYONE (Game Officials, Players, Coaches, Cheer Leaders, Spectators, Passers By from BOTH sides). Forfeiting, or suspending, a game for legitimate "Safety" concerns is a serious, but prudent, response if/when circumstances merit such decisions. Either are "Administrative Decisions" subject to review and potential, subsequent, modification.
Judgments on such decisions should involve consideration of the specific circumstances, the potential, and risk, for possible escalation and/or continuation or repetition of the behavior responsible. Such discussions, where possible, should involve consultation with appropriate Administrative personnel from BOTH schools.
However, the ultimate decision, as to the general safety of continuation of the contest, at that time and location, are addressed in NFHS: 1-1-6, advising, "The referee's decisions are final in all matters pertaining to the game."
