From the 2005-2006 NFHS Basketball Interpretations:
SITUATION 12: Team B has just scored to go up by three points with time running out in the fourth quarter. Player A1 inbounds the ball to A2 close to the sideline of Team B's bench. A2 releases a three-point try just prior to the horn sounding. Substitute B7 leaves the bench area, enters the court and blocks the shot.
RULING: B7 shall be charged with two technical fouls and ejected. One technical foul is assessed for entering the court without permission and one for unsporting conduct. Any member of Team A may shoot the four free throws for the technical fouls. The results of these free throws will determine if the game is over or going into overtime.
COMMENT: Two technical fouls must be assessed in this situation. Otherwise, the team committing the infraction would benefit from the act. (10-4-1; 10-4-2)
