Speaking of correctable/non-correctable errors

[Nevadaref]

Rich,
I know that you know this, but for others who may read this thread here is the official NFHS ruling for that scenario.

2004-05 NFHS Basketball Rules Interpretations

SITUATION 3: A1 is fouled by B2 and is awarded two free throws. The foul is B2’s fifth foul. The new trail official reports the fifth foul to Team B’s coach. Before a substitute is made, the lead official incorrectly permits A1 to attempt the first free throw. The officials realize the error and huddle to discuss the situation. RULING: The result of the first attempt shall stand. Team B’s head coach shall be notified of B2’s disqualification. Once B2 has been replaced, A1 shall attempt the second free throw. COMMENT: This is an official’s error and not a correctable-error situation according to Rule 2-10. (2-8-3, 4-14-1, 6-1-2c, 10-5-1d)
