Rule Changes through the Years



2-3-2:  A pliable artificial tee is legal.

2-11 and 8-2-1:  Failure of A to have 7 players on the line is a form of offside.  Ball does not remain dead.

3-5-1 and 2:  A substitute may enter during any dead ball if substitution is completed before snap or free-kick.  If clock is running, not more than 2 substitutes from the same team may enter.  If certain infractions are discovered late, time of discovery determines spot of enforcement.

5-2-7 and 6-6-1:  Penalty for invalid fair catch signal is loss of 5 (instead of 15).

6-3-2 and 5:  If fumble or backward pass goes out of bounds between goal lines, ball belongs to the team which fumbled or passed (unless lost on 4th down).  This applies even if ball is touched by the defense.

8-1-2-b:  Snapper may lift end of ball to not more than 45 degree angle if done when he first grips ball and if such lifting is not part of the snap.


2-21-2:  Rewritten to aid officials in determining when a bat or muff of a kick is a new impulse.

2-27:  It is a shift when a player moves from the line to a new set position.

3-5-2:  For most illegal substitutions, ball does not remain dead and whistle should not be blown.  But, if three or more substitutes enter illegally, or if a team has more than eleven intended participants on the field, Referee may blow whistle immediately.

4-3:  Slight changes cover situations where one foul is simultaneous with snap or free kick and a second foul occurs during succeeding play.

4-4-1-3:  A note makes it clear that penalty for foul which occurs simultaneously with snap or free kick is from spot of snap or free kick.

6-1-2:  Rewritten to make it clear that ball does not remain dead for a number of fouls which occur simultaneously with snap or free kick.

6-6-1:  Fair catch signal is valid only when hand is waved sidewise while held at arm’s length above the head.

8-1-4:  A new article provides penalty for attempt by linesman of A to draw B into neutral zone.

8-2-4:  This article has been placed under Section 2 because ball does not remain dead for these infractions.  Also, last year’s Item 3 which limited position of center, guard and tackle has been omitted.

8-4-2:  An addition to this article provides coverage for a recovered return kick.  Rights of kickers are nearly the same as for a kick from scrimmage.

9-4-a:  Team which makes a return kick may score if drop kick is used.


*This rules book edition was an entire recodification so only significant changes are listed

Side zone is 53 feet 4 inches wide.

Handing the ball forward is not a forward pass but is sometimes illegal.

Ball may be kicked from beyond the neutral zone.  Team may take 4 legal time-outs per half.

Ball must be put in play 25 seconds after it is ready.

There are several differences in the substitution rule.

For a foul prior to a snap or free-kick, Referee blows his whistle only if there is a chance to prevent the snap or free-kick.

Foul by B does not result in automatic 1st down except for forward pass interference or foul during a backward pass or fumble.

If a free-kick goes out-of-bounds a second time, ball is awarded to R on their free-kick line.

Basic enforcement spot for foul during a run is spot of dead ball, regardless of which team is in possession at the end of the down.  Also, penalty for foul during a backward pass or fumble is loss of ball at spot of foul.  (See the supplement for detailed list with comments.)


2-1-4:  Any ball which is not in player possession (kick, pass or fumble) is a loose ball.  A live ball is always in possession of one team or the other.

3-3-3:  If the Defense fouls during the last down of a period, the period is extended if penalty for a foul by the Defense is accepted.

6-1-2 and 4:  A free-kick must be made from on (rather than anywhere behind) A’s free-kick line.  Also there is a 5-yard penalty for making a short free-kick.

6-1-8:  A second free-kick is not permitted when the first goes out-of-bounds.  Instead, it is R’s ball at the inbounds spot or at the inbounds line 10 yards behind R’s free-kick line.

6-3-2:  Right of either team to touch recover and advance a return-kick is the same as their rights during a scrimmage-kick with the yard line through spot of the kick being substituted for the scrimmage line.

7-5-2-c and 7-5-6:  When a forward pass is touched by an ineligible who is on or behind his scrimmage line, it is not pass interference.  If he catches or bats the pass, it is an illegal forward pass with penalty of 5 yards and loss of down.  Pass interference can now occur only beyond the line.

8-1:  If a game is forfeited when the offended team is in the lead, the score at time of forfeiture is final.

8-3-1:  A try-for-point is made from on B’s 2 yard line (rather than from anywhere behind it).

8-5 and 9-1:  These sections have been rewritten for clarity and accuracy.

10-3 and 4:  All action during a live ball is either a running play or a loose ball play.  Basic enforcement spot for a foul during a running play is at spot where the run ends (not always the same as spot of dead ball).


1-3-1:  Ball measurements as stated prior to 1948 are given.  Current top-grade balls conform to these measurements. 

1-3-2:  Tan ball with one-inch wide white stripes is mentioned.

3-3-4:  Now states that only a foul by the Defense or fair catch interference can cause a period to be extended. Making a fair catch does not extend such period.  The fair catching team may snap or free kick to start a 2nd or 4th quarter.

3-5-2:  Revised to indicate that the cause for stopping the clock determines whether it is started when ball is ready or when it is snapped.

3-7-2 and 3:  Substitution rights are now the same for any time-out regardless of whether an injured player is removed.

4-2-2:  Items c, d, e and f are revised to conform to two changes, i.e., any player may recover and advance a backward pass or fumble as in 7-4-2, and any kick, including a free-kick, becomes dead when it touches something on or behind R’s goal line as in 6-1-7.

6-3-1:  Team A cannot kick from beyond the neutral zone unless team possession has changed.

6-4-2 and 5:  A fair catch cannot be made after a muff by R has been touched by K.

7-3-2:  Player of A on an end of his line may receive a forward handed ball without turning to face his goal and without being a yard behind the line.  This right exists, provided he is not the snapper nor the player adjacent to the snapper.

7-5-6-Pen:  If pass interference by either A or B is also unsportsmanlike, an additional 15 yards is assessed.

9-3-g:  If a team is not ready to start a half on time, it is unsportsmanlike conduct.

4-2-2-d, 6-1-7, 6-2-8 and 8-4-1-b:  Revised to remove past exceptions.  Touching of an attempted field-goal by K on or behind his line is ignored.  Also, touching of an attempted field-goal by R behind his goal line kills the ball.

4-2-j and Page 55:  All officials are authorized to use a whistle to declare ball dead in certain specified situations.

3-7-2:  Player may not withdraw and enter or enter and withdraw during same dead ball.

6-1-6 and 6-2-7:  If kicked ball becomes dead inbounds with neither team in possession or with opponents in joint possession, ball belongs to R.

6-2-4:  After first touching of a kick by K, if R secures possession and thereafter commits a foul, the first touching is ignored.

6-4-2 and 4:  If R1 signals for fair catch and kick is caught by R2, it is a fair catch.  R2 cannot be tackled unless tackler had no reasonable opportunity to see the signal.

7-5-6:  Addition to 1st paragraph extends interference restriction for Team A in case more than one legal forward pass is thrown.

8-3-4:  If try-for-point is replayed after a penalty, ball is put in play between the inbounds lines.

10-5-2:  Typographical error of last year has been corrected.


1-3-1:  Either team may use its favorite type ball when they put ball into play.

3-4:  The revision requires the removal of any injured or apparently injured player for at least one down.  Official is authorized to stop the clock for a player who appears to be injured.  Discovery of an injured player when the clock is stopped and the ball is dead does not cause his team to be charged with a time out unless the injured player’s replacement delays the ready-for-play signal.

9-6:  Expanded note urges Officials to penalize promptly any unsportsmanlike conduct on the part of any one officially associated with the team during any period or during any intermission.

2-4:  The area in which it is legal to block from the rear has been reduced to 4 yards laterally on each side of the snap and 2 yards behind each scrimmage line.  In order to legally block from the rear within this rectangle (8 yards by 4 yards), the blocker must be in the area at the time of the snap.

3-4-1:  An addition specifically authorizes stopping the clock for an Official’s time-out when there is “any unusual delay in getting the ball ready-for-play.”

6-4-2:  A revision provides that only the player who signals can make a fair catch.  The ball becomes dead but it is not a fair catch if a teammate catches the ball.

7-5-6:  Ineligible pass receivers may advance beyond the scrimmage line as soon as the last forward pass leaves the passer’s hand.  Ineligible continue to be restricted from touching a forward pass before it has touched B.

6-1-8:  Receivers are required to put ball in play at inbounds spot if R is last to touch free-kick which goes out-of-bounds between goal lines.

6-2-4:  An addition specifies the right of R to take the ball at spot of first touching by K is nullified if penalty is accepted for any foul committed during the down.

9-4-1:  The word “voluntarily” has been deleted.  The article now provides that unless a player is pushed or blocked out-of-bounds during a down, he will participate illegally if he touches the ball or hinders an opponent after having been out-of-bounds.

Football Official’s Signals and Summary of Penalties:  Two additional signals have been added and the signals have been renumbered.  Signal No. 8 is to signify grasping an opponent’s face mask and Procedure Signal E is used to designate an Official’s time-out.  The Penalty Summary Chart has been completely revised to correlate with the renumbered signals and rules changes.

3-3-4:  If there is fair catch interference during the last timed down of any quarter, the quarter will be extended if the penalty is accepted and it may be extended if the offended team accepts an awarded catch.  The offended team has three choices.  If the penalty is accepted, the kicking team will be required to replay the down, untimed, in an extension of the period.  If the offended team chooses to take an awarded fair catch, it may make a free-kick, or it may snap the ball for an untimed down during the same period.  If the fair catch interference is not during the 2nd or 4th quarter and if the offended team elects, it may put the ball in play by snap or free-kick on the 1st down of the next period.

3-4-1:  The clock will start following a free-kick, when the ball is legally touched.

Responsibilities and Procedures of Officials:  Revisions have been made to accommodate additions to the referee’s responsibilities for: (1) appointing a clock operator; and (2) correcting obvious errors in timing.

7-1-3:  Snapper may tilt the ball to an angle of not more than 45 degrees.
