A1 walks off under his own power to the bench. Coach A asks if A1's substitute can shoot the free throws, and later have A1 enter the game. What are the rules governing this situation? I have searched the books, but have not found anything.

Once the trainer, and coach, come out onto the court, then A1 must be replaced (assuming an eligible substitute is available), or Team A must request, and be granted a timeout. If replaced, A's substitute will shoot the free throws, and A1 may reenter the game after the clock has been started properly.

3-3-4: A player who has been replaced, or directed to leave the game shall
not re-enter before the next opportunity to substitute after the clock has been
started properly following his/her replacement.

3-3-6: A player who has been injured to the extent that the coach or any
other bench personnel is beckoned and/or comes onto the court shall be directed
to leave the game, unless a time-out is requested by, and granted to, his/her team
and the situation can be corrected by the end of the time-out.

8-2: The free throw(s) awarded because of a personal foul shall be attempted by the
offended player. If such player must withdraw because of an injury or
disqualification, his/her substitute shall attempt the throw(s) unless no substitute
is available, in which case any teammate may attempt the throw(s) as selected by
the team captain or head coach.
