Position on the sideline on K's free kick line, opposite the Linesman.

Be responsible for your sideline to the kicker's goal line.

Be responsible for your sideline to the kicker's goal line in the event of a long return.

Key the snapper and guards. If they block aggressively, read run. If they pass block, read pass.

Read the point of attack.

When the play is wide to one side, do not watch the ball — move in that direction observing the initial line play and action around the runner. Remain on the inside working out to maintain boxed-in coverage.

When the hole opens directly in front of you, do not watch the ball — react and adjust, possibly moving laterally from the hole and being alert for the tight end cutting across.

Cover action at the point of attack and then behind the runner.

Check for illegal use of hands or other fouls near the neutral zone.

Be alert for a quick kick or pass, ineligible receivers, and touching by Team B of a forward pass behind the line.

If a fumble occurs beyond the neutral zone, assist in determining who secures possession.

When the ball is dead — move toward its location. Be positive of the ball's location before sounding the whistle. The Umpire's whistle should rarely be the first whistle at the end of a play. Help spot the ball.

Following a scrimmage play when the line-to-gain is reached, if the offense is moving fast, stay over the ball until waved back by the Referee, then back pedal to your pre-snap position.

Before the snap: same as a running play.

Be alert for illegal contact on the snapper.

Be alert for Team B committing an encroachment foul by touching the ball or snapper's hands prior to the snapper releasing the ball.

Watch for illegal contact and illegal use of the hands and holding.

When you read forward pass, step toward the neutral zone — this removes you as a target on shallow drag routes and puts you in position to rule on ineligibles illegally downfield.

Observe action of the players in and just behind the neutral zone.

Secondary responsibility: assist in determining whether the passer's feet were in or behind the neutral zone when the ball was released.

Turn to cover short passes down the middle.

Know where the forward pass first touches anything. If the ball is touched by Team B, give Signal 11 — the tipped pass signal.

Always know the previous spot and assist in getting the ball back to that spot for the ready-for-play after an incomplete pass.

Secondary responsibility for the intentional grounding exception (Rule 7-5-2d Exception 2) — assist the Referee by brief conference as to whether the pass reached the neutral zone extended.

Position less than 8 yards deep, favoring the Line Judge's side of the field.

Count Team K players — confirm using closed fist with the Referee.

Check for the numbering exception.

Give a verbal warning — 'Do not foul the snapper' — to the defensive player over the snapper.

Key the offensive guards and snapper.

Step toward the neutral zone, first observing action on the snapper, then shift to the offensive guards and backs behind the neutral zone.

If the snap is mishandled or there is a question whether the kick will be made, move to the neutral zone to assist the Linesman if the ball crosses the line, or assist the Referee if the kick is blocked.

Be alert for a run or pass. Be alert to assist the Referee in covering a short or blocked kick.

Following the kick, pivot to view the Line Judge's side of the field to observe blocks away from the ball.

Be alert for fouls in the secondary and move downfield slowly.

When the ball goes out of bounds, move to a position to help relay the ball to the inbounds spot.

Position less than 8 yards deep, favoring the Line Judge's side of the field.

Count Team K players — confirm using closed fist with the Referee.

Check for the use of the numbering exception.

Key the action of the snapper and guards. Watch for illegal leg locking.

Step toward the neutral zone, reading the interior linemen.

Check action on the snapper — illegal action by the defensive man over the snapper.

Be ready to assist the Referee in covering a short or blocked kick.

If a running or passing play develops: be alert for action on or by outside offensive linemen and the front-most blocking back on the vacated Line Judge's side; shift observation to contact between defensive players and blockers behind the line; pivot to view the Line Judge's side and observe blocks in the side zone; assist in goal line coverage if a run develops to the Line Judge's side.
