A1 is fouled by B1 while Team A is in double bonus. In frustration, A1 pushes B1 after the ball becomes dead. A1 is assessed a technical foul. A1 successfully makes both free throws for the personal foul assessed to B1. B3 is ready to attempt the free throw for the technical foul by A1. The official scorer notifies the officials that the technical foul on A1 was his/her fifth.

RULING: Officials notify the Team A coach and A1 of the disqualification and allow a substitute for A1. A correctable error has occurred by allowing the wrong player (A1) to attempt the free throws for the personal foul and has been discovered within the timeframe to correct. The free throws by A1 are cancelled and A1’s substitute shall attempt the free throws for the personal foul against A1 followed by the attempts by Team B for the technical foul. (2-10-1c, 4-14-1)

I think this falls into the category of "unannounced change".
