PF on TD Run

[golfdesigner]

Had this one yesterday..
A23 is running for TD, B75 is called for personal foul, well behind play but before A23 crosses goal line..
R throws Flag..then U signals TD..R goes to A captain and gives choice the 15-yards for the PF could be assessed on the try or on the kick-off..

When the end of the run is a TD, I thought the foul is assessed on the succeeding spot, which would be the try..

The PF was assessed on the Kick-off, with A kicking from B's 45-yd line..

Did we get that one right?
I haven't had chance to look it up in the books.

NFHS Rules, sorry guys.
