Article 8 – Deliberate Grounding
a) Field of Play
If the passer in the field of play deliberately throws the ball out of bounds, or to an area where there is no eligible Team A receiver, apparently to avoid a loss of distance, penalize as for an offside pass.
Penalty: 1.2D – LD AT POP, 3D – LB POP.

b) End Zone
If the passer in the end zone deliberately throws the ball out of bounds, or to an area where there is no eligible Team A receiver, penalize as follows:
Penalty: 1.2.3D – Safety touch to Team B, or option to decline the score, and accept the play as an incomplete pass.
