Illegal Substitution

[Nevadaref]

The coach is clearly right. The Trail handled it correctly. This is a plainly written rule and there is no reason that it shouldn't be enforced. At the HS level, the players and coaches are expected to know this.

RULE 10, SECTION 2 SUBSTITUTE TECHNICAL
A substitute shall not enter the court:
ART. 1 . . . Without reporting to the scorer.
ART. 2 . . . Without being beckoned by an official, except between quarters.
PENALTY: (Section 2) Two free throws plus ball for division-line throw-in. One foul for either or both requirements. Penalized if discovered before the ball becomes live.
NOTE: A single flagrant technical foul or the second technical foul charged to a substitute results in disqualification of the offender to the team bench.
