Punt
Gunner is running parallel to the goal line trying to keep ball out of EZ.
Left foot steps on the goal line.
With left foot now not touching the goal line he dives and bats the ball. Note that no part of his body had touched the field of play after his foot hit that the goal line and before he touched the ball.

Touchback?

I am not an official. Just curious as to what is required after touching the goal line before you can touch the ball.

Thanks
