Yes it is confusing.
Rule Book -- 9-6-4 G
It is illegal Participation...
g - For a player whose helmet comes off completely off during a down to continue to participate beyond the immediate action in which the player is engaged
Penalty Art 1.2.3.4a,g - 15 yards, live ball basic spot.
Then I read Rule 10:
Basic Spots
Art. 4 - The Basic spot is the spot of the foul for:
B: Illegal participation - as in 9-6-4a and 9-6-4g
What am i missing ??
Thanks
