Halftime Intermission Option Following Weather Delay [3-1-6c EXCEPTION (NEW)] — The halftime intermission may be shortened by mutual agreement of opposing coaches if a weather delay occurs during the last three minutes of the second period.

40-Second Play Clock Clarification [3-6-1a(1)e EXCEPTIONS 2 and 3 (NEW)] — To eliminate a potential timing advantage gained by the defensive team, the rules committee approved the play clock being set to 40 seconds when an officials’ time-out is taken for an injury to a defensive player or a defensive player has an equipment issue.

25-Second Play Clock Clarification [3-6-1a(1)f (NEW)] — Following a legal kick when either team is awarded a new series, the play clock will be set to 25 seconds.

Disconcerting Act Foul and Penalty Reclassified [7-1-9 (NEW), 7-1-9 PENALTY (NEW)] — Disconcerting acts or words by the defense has been reclassified from a unsportsmanlike foul to a disconcerting act foul, and the penalty changed from 15 yards to 5 yards.

Spiking the Ball to Conserve Time (7-5-2e EXCEPTION, TABLE 7-5-2e EXCEPTION, TABLE 7-5e EXCEPTION) — The exception to allow a player to conserve time by intentionally throwing the ball forward to the ground immediately after receiving the snap, has been expanded to include any player positioned directly behind the center. This exception now includes snaps that are not hand-to-hand.
