1. At the beginning of the first half and the second half, or after scoring goals and trying, the opening team should kick off from the team's 30-yard line. Kick-off is a free kick.

2. You can use the 1 inch ball pad when kicking off (it is not allowed to use the ball pad when kicking the target score, the safe score or the trial kick with the ball). Kick the ball with a positioning kicker.

3. You can't get the target score when you kick off.

4. If the tee-off distance does not exceed 10 yards or is not touched by the receiving team, then the tee-off is considered illegal. Once the kick-off is touched or passed by the receiver over 10 yards, the ball becomes a free ball. The catcher can take the ball back and push it. Kicking teams can get the ball back, but they can't push the ball unless the receiver controls the ball and loses it.

5. If the kick-off is out of bounds within two goal lines and is not touched by the receiver, the ball belongs to the receiver 30 yards away from the ball point or where the ball is out of bounds, unless the ball is out of bounds for the first time when kicking "self-kick". In this case, the kicker will be fined 5 yards before kicking the ball.

6. If the kick-off is out of bounds in two goal lines, but it is touched by the receiver, then the ball belongs to the receiver whose ball is out of bounds.

7. If the opening team kicks off to the borderline illegally, or kicks a short-distance free kick in two or more consecutive self-kicks, then the receiving team can get the ball at the dead ball point, or where the ball is out of bounds, or at the illegal touch point.

(6) Safety score

1. In addition to kick-off, another free kick is a kick after a safe score. You can use fly kick (but not kick off).

2. In terms of scoring safety, the team can score by kicking in the air, throwing the ball (referring to throwing and kicking the rebound ball) and kicking the positioning ball without the ball pad. After scoring a safe score, you can't kick the ball at will, even if a series of punishments put the team in such a situation. It is only possible to score a goal by kicking a free kick after fighting for the ball or legally catching it.

(vii) Fair catch.

After legally receiving the ball, the receiving team can choose to kick off; Or kick "legal catch kick" at the legal catch kick line outside 10 yards to get the target score. When you strive for a goal, all the general rules apply. Start timing when kicking the ball (no cushion is allowed).

(8) Fouling at the final stage of the half-court or full-court game.

1. The defender fouled. If he accepts the punishment, he will touch the ground again.

2. If the attacker fouls and does not repeat the touchdown, the touchdown is invalid.

Exception: The attacker will not score if the ball is caught, fouled or illegally contacted and the possession of the ball is transferred.

(ix) Foul point

1. Four basic foul points:

(a) the place where the foul occurred

(b) Front foul point: the place where the kick-off takes place.

(c) the place where the ball is contested, returned or conceded; Foul punishment department

(d) Continuous point: If the ball is pushed again during the blowing penalty, the kick-off place is the blowing penalty place.

2. If the attacker fouls behind the line of scrimmage (except in the touchdown area), he will be punished for kicking off at the previous service point. If the ball is in the touchdown zone, it will be a safe ball.

3. If the defender fouls with the ball or unreasonable hand after the line of scrimmage, if he fouls outside the line, the penalty code will be calculated online.

(x) Two fouls

1. If you commit two fouls when handing over the ball, the player who finally gets the ball before the exchange will win the ball.

2. If there are two fouls after the exchange, the defender gets the ball at the foul or dead ball.

3. If one of the two fouls is unqualified, the fouler must be sent off, but not fined.

4. The player fouls before exchanging possession of the ball, the receiver fouls after the exchange, and the receiver gets the ball.

5. When a team scores on the ground, scores a goal, gets extra points or safety points, the other team member fouls, is disqualified as an athlete, or makes unreasonable moves when falling on the ground, and makes a free throw at the kick-off.

(XI) Emergency events

Members, officials, employees, players and coaches of the NFL should watch every game, and the NFL will decide whether to continue the game. In case of unexpected events, such as severe cold weather, natural and man-made disasters, power failure, audience interference, etc. When the start or continuation of the competition will pose a threat to the safety of contestants and spectators, the competition will be suspended, cancelled, postponed or terminated.

* Cancel. Cancelling a game is to invalidate it (whether before or after the game starts), and there is no intention to reschedule the game or include its scores and other performance data in the team's records.

* Delay. Delaying the game means (a) delaying the start time of the game, or (b) pausing the game after the game starts, and preparing to restart it later. All scores and other performance data before the pause are added to the scores and data after the game is resumed.

If the environmental conditions of the day have been determined, the representatives of the League should still consult with the Meteorological Bureau and the appropriate security personnel of the League, clubs, stadiums and local governments.

(13) Steps for starting or rematch.

The main points of the right to handle such affairs are as follows: under the influence of special emergencies, the labor union personnel department and the referee will start or replay according to this step.

1. Due to unexpected events, a regular season or playoff game cannot be kicked off as scheduled or delayed on the same day, and the game still needs to be arranged by the Committee on the following date.

2. If an emergency (such as an upcoming tropical storm) is expected to occur after or during the competition, the start time shall not be arranged in advance unless there is obvious or sufficient time to make orderly changes.

All suspended games will be resumed on the same day. If all competitions are postponed to another date, it will start from the moment of suspension. When the game is suspended, the referee shall announce the suspension and record the following data: the team that controls the ball, the direction of the ball, the position, area, distance and time of the game when the ball is present, and any data and information related to the fair start.

4. The Committee will postpone the regular season again in the same venue within two days of the original match day. If it cannot be held in the same venue, the organizing Committee will arrange a reasonable alternative venue competition. If the match can't be replayed within two days of the original time, it will be arranged for the rematch next week. If the players of both sides play because of time conflict, the Committee will arrange unfair competition time. (For example, the game has been scheduled for Tuesday)

For the postponed playoff, the committee will be held in the same venue as soon as possible after the scheduled game. If it is impossible to play in the original venue, the Committee will arrange a reasonable venue to arrange a rematch.

In any case, if the game is postponed due to the negligence of the club, the club will bear the expenses of the home team, including the comments of the Committee, tickets and TV broadcast income.

Any club must strictly protect the venues and stadiums to make them suitable for NFL games.
