Can you change this call?

Sounds to me like the whistle is before the ball is caught. If this is the case, they can accept the penalty of pass interference(enforce from the line of scrimmage) or they can decline it and replay the down.

If the player was in possession at the IW, he can either accept the penalty and enforce from line of scrimmage, decline the penalty and have the ball where it is or decline the penalty and replay the down.

I think that's right, anyone elses thoughts?
