It is not a safety if a player between their own team’s five-yard line and goal line:
(a) intercepts a pass or fumble; or recovers an opponent’s fumble or backward pass; or catches or recovers a kick; and
(b) the player’s original momentum carries that player into their own end zone; and
(c) the ball remains behind that team’s goal line and is declared dead in that team’s possession there. This includes a fumble that goes from the end zone into the field of play and out of bounds (Rule 7-2-4b-1).
If conditions (a)-(c) are satisfied above, the ball belongs to this player’s team at the spot where that player gained possession.
