Punt ruling

[Jaysef]

4th and 15 for A, A's scrimmage kick is a line drive that hits B lineman and ball deflects: (a) beyond the expanded neutral zone, where it is recovered by A. (b) behind the neutral zone, recovered by A. (c) Out of bounds

This occurred in a 5th/6th grade game, and the officials gave ball to A, 1st and 10.

NFHS cites a condition (not sure where, I don't have my book), where touching is ignored on a line drive punt.

Therefore, I have B's ball in all situations. Any thoughts?

Same ruling if A's lineman was the recipient of the fast ball to the helmet?
