I'm new to officiating, just officiated my first games, JFL, this past weekend. I have a question regarding the extended goal line. My understanding is that the runner can hold the ball over the sideline (out of bounds) and as long as he has both feet in bounds as he crosses the goal line, this is a touchdown, as the goal line is extended on this play? What is the ruling if, while still holding the ball over the sideline and both feet in bounds, the ball becomes loose, but continues forward, at the one yard line and breaks the extended plane? Is it a fumble at the spot or would it be a touch back for the opposing team?
