Fumble Out of End Zone Into Field of Play Resulting in Safety NFHS Rule 8-5-2
 

Under the current 2025 NFHS Football Rules, when Team A fumbles the ball in its own end zone, then goes forward into the field of play, and Team B bats or muffs the ball out of bounds beyond
the goal line (e.g., at the 1-yard line), the play results in a safety against Team A. This ruling is based on Team A’s original impetus for the ball entering the end zone.

Suggested correction, if a loose ball originating from a fumble by Team A in its own end zone and crossing the goal line in the field of play and is subsequently batted or muffed out of bounds by Team B,
the result is not a safety. In such cases, the ball is declared dead at the spot where it crossed the sideline, and Team A retains possession or Team B possession if 4th down.

That's not the problem, so not correcting the problem. The problem is the illegal forward pass's wiping out responsibility for the ball's being there in cases where it would've been a touchback had the fumbling player gone down with the ball. So the illegal movement of the ball gives the team making it a worse outcome than making it dead would have.

The solution is to have fouls that incur loss of down not supersede "responsibility".
