"While in the process of a substitution (or simulated substitution), the offense is prohibited from rushing quickly to the line of scrimmage and snapping the ball in an obvious attempt to cause a defensive foul (i.e., too many men on the field). If, in the judgment of the officials, this occurs, the following procedure will apply:
(a) The Umpire will stand over the ball until the Referee deems that the defense has had a reasonable
time to complete its substitutions.
(b) If a play takes place and a defensive foul for too many players on the field results, no penalties will be
enforced, except for personal fouls and unsportsmanlike conduct, and the down will be replayed. At
this time, the Referee will notify the head coach that any further use of this tactic will result in a penalty
for unsportsmanlike conduct."
