We've had a lot of questions on this ruling today. Seems like most of them are dealing with the receiver illegally touching the pass once he has returned because he's an ineligible reciever.
If you look in the fundamentals you'll see a key part to this question.
VII. Passes
1. A player who is eligible at the start of the down remains eligible throughout the down.
I hope this will help everyone one.
What do you think?
