foul as horn sounds...

[Man in Grey]

I have to correct myself, this is the rule:

34.2.2
If the foul is committed on a player in the act of shooting, that player shall be awarded a number of free throw(s) as follows:
• If the shot from the field goal area is successful, the goal shall count and one (1) additional free throw awarded.

• If the shot from the two-point field goal area is unsuccessful, two (2) free throws will be awarded.

• If the shot from the three-point field goal area is unsuccessful, three (3) free throws will be awarded.

• If the player is fouled as, or just before, the game clock signal sounds for the end of the period or as, or just before, the twenty-four second device signal sounds, while the ball is still in the player's hand(s) and the field goal is successful, the goal shall not count and two (2) or three (3) free throws will be awarded.

So only when the shot is released, when the foul is called, it can be a fieldgoal.
