Injured Shooter?

Your partner is wrong.

DESIGNATED FREE THROWER
8.2 COMMENT: When A1 is designated to attempt a free throw(s), no other player shall be permitted to make the attempt unless A1 is injured or disqualified prior to the attempt. If the wrong player attempts the free throw, it may be corrected as prescribed in 2-10. In certain situations, the attempt by the wrong player may be due to a justifiable misunderstanding. In such case, there should be no penalty. But, if it is a situation in which it is reasonable to expect the player to know that he/she is not the proper one to attempt the free throw, a technical foul for unsporting conduct shall be called. In this situation, the proper player is entitled to his/her free throw(s) which will be followed by the administration of the technical foul. (10-3-7f)
8.2 SITUATION: A1 is unable to attempt either of the two free throws awarded because A1 was injured during the play. A6 enters, replaces A1 and attempts the first free throw. A7 reports and enters to replace A6. RULING: A7 must return to the bench and A6 remains in the game to attempt the second free throw. Since A6 replaced A1, A6 must shoot both free throws, unless A6 is injured or disqualified before attempting the second free throw. If this situation involved technical foul free throws, A7 would be allowed to enter and attempt the second free throw. (8-3)
