NFL will look at the fumble-out-of-end-zone rule

The rule should be - you fumble out the side of the end zone, it’s treated like a fumble out of bounds under 2-minutes. It’s returned to the spot of the fumble.

If it’s fumbled out the back - it’s a touch back - because your team should have had ample opportunities to recover in the 10 yds from the goal line to the back of the end zone.
