Tackling.

There shall be no tackling below the knees, except by the men on the line of scrimmage on the defense, and of these, the two men occupying the positions on the ends of the line may not tackle below the knees.

Rulings on Penalties.

It shall be the duty of all officials to penalize the offenses enumerated under the caption of unnecessary roughness, unsportsmanlike conduct, or disqualification.

Whenever the rules provide for a distance penalty that would carry the ball across the goal line or nearer to the goal line than the 1-yard line, the ball shall be down on the 1-yard line. If, however, a foul be committed inside the 1-yard line, half the remaining distance to the goal line shall be given for each offense.

In case more than one official signals a foul against the same side during the same scrimmage, the sum of the penalties shall be inflicted.
