Is it possible?

[Johnny Ringo]

What I am looking for here is if the following scenario is true ...

A1 trys for a goal ... once the ball is gone, the time expires, the horn sounds and just after that B1 hacks A1 (A1 was still an airborne shooter) resulting in the official to blow the whistle to call a foul.

This results in A1 going to the FT line to attempt the FTs with 0.0 on the clock.

Sound legal and proper under the rules?
