Another potential Illegal Participation play

[l3will]

My thinking is that K99 chose to go out of bounds and he chose to stay out
of bounds... when he reaches back in to the field of play while still standing
out of bounds he violates the spirit of the rule. 9-6-2.

So what would you do... declare it dead at the one even though the kick would have crossed the goal line.?

Great play for thought...

I'd might even invoke 9-9-1...
A player or nonplayer or person not subject to the rules shall not hinder play
by an unfair act which has no specific coverage. In this case probably declare
it a touchback .

My thought, your opinion may vary
