A1 is fouled by B1 while in the act of shooting and the try or tap is successful. The administering official erroneously awards and announces two free throws instead of one. A1’s first attempt is unsuccessful and B1 rebounds. Play continues briefly with B1 advancing the ball before the official recognizes the error and stops play.
Since A1 has attempted the merited free throw he/she was entitled to, there is no further correction to be made. Play shall resume with a throw-in by Team B at the out-of-bounds spot nearest to where play was interrupted.
