American Football Rules IFAF Approved Ruling 6-3-14:I-II

I. Fourth and seven at the B-20. Team A is in a formation to attempt a field goal. Defensive linemen B55, B57, and B78 are shoulder to shoulder. B57 is head up on right guard A66 while B55 and B78 are in the gaps on A66’s left and right shoulders, respectively. After the ball is snapped all three move forward together. (a) The three make their primary contact against A66; (b) B55 and B57 contact A66, and B78 drives at the right offensive tackle; (c) B57 and B78 make their blocks against A66 but B55 leaps to try to block the kick.
RULING: (a) Foul. Five-yard penalty. If Team A accepts the penalty they will have fourth and two at the B-15. (b) and (c) No foul. The action by the Team B players does not involve primary contact against a single player, and hence the play is legal. [Cited by 6-3-14]
