Fumble Advanced for a Touchdown

[JAZZMAN]

Our state clinician is on the FEDERATION rules committee and he told me since the first run did not end in the endzone that the penalty would be the end of that run. If the runner had not fumbled, but had HANDED the ball to another teammate and then the touchdown been scored, the endzone would have been the end of the run with enforcement on the try.
I have heard it said that officiating football isn't rocket science, but it isn't basketball either!
