(3) Foul and its punishment

1. Technical foul

A player's immoral behavior or violation of rules on the court or bench is a technical foul. Illegal contact with opposing players before the ball survives can also be judged as a technical foul.

(1) Behavior without sportsmanship

Any athlete, coach or trainer who has no sportsmanship may be fined up to two technical fouls. Any violator who has no sportsmanship once can be dismissed; In both cases, immoral behavior must be expelled.

Sportsless behavior, such as: it is impolite to talk to the referee; Physical contact referee; Express public dissatisfaction with the verdict; Use obscene language; The coach entered the venue without the permission of the referee; Stretch your elbow intentionally or try to tamper with it, but it doesn't involve contact.

There are also some technical fouls that are not caused by immoral behavior, such as: delaying the game; Violation of the team seating area; When the ball becomes a dynamic ball, the number of people on the field is not enough or more than 5; The attacker deliberately hangs on the basket or backboard and so on.

Touching the ball illegally during the dead ball, if it is considered immoral, can be sentenced to technical foul; If the contact is unnecessary and excessive, it can be judged as a malicious foul.

(2) Foul in a fight

If there is a fight between a player, coach or trainer during the game or during the dead ball, you should remember the technical foul and not award a penalty. Those who take part in the fight should be fired immediately. In addition, according to the situation, the fighter will be fined not more than $20,000 and suspended.

In NBA games, the penalty for foul is more severe. An athlete, coach or trainer can be dismissed under the following circumstances: the elbow foul is at or below the contact shoulder level; Technical foul without sports moral behavior; A malicious foul caused by unnecessary or excessive contact.

Athletes, coaches or trainers must be dismissed if they commit the following acts: boxing foul; Foul in a fight; Elbow foul is higher than the level of contact shoulder; Trying to punch without contact; Not the continuation of the game, but deliberately entering the stands.

In order to punish and stop fouls, there are also provisions on fines in NBA rules.

Violation of the regulations will be judged as a personal foul and will be punished according to relevant penalties.

(1) foul by both sides

Foul on both sides refers to the situation that two players who are not on the same team commit personal or technical fouls on each other almost at the same time.

Fines:

No matter personal or technical fouls, no penalty will be awarded, only the fouls of the players will be registered, not the fouls of the whole team. If a team owns the ball when both sides are convicted of a foul or a fight foul, it should keep the ball and throw a foul ball on the sideline near the place where the game was interrupted to continue the game. If neither side owns the ball when the foul is declared, or the ball is in the air when the shot is missed, any two players from different teams should jump the ball in the middle circle to continue the game. If the shot is successful and the score is valid, throw the foul ball at the baseline to continue the game. If the foul of both sides is the result of different opinions of the referees, no points will be scored, and any two players from different teams will jump the ball in the middle circle to continue the game.

(2) Offensive foul

After the ball survives, the attacking player makes illegal contact with the opponent, which is an offensive foul.

Personal foul of the attacker, if not elbow foul, boxing foul, or malicious foul, should be dealt with as follows: the attacker does not score; Register a foul player and commit a personal foul; Do not register the team's in-team foul (except for the sixth personal foul of the team and the team has no qualified substitute).

(3) foul without ball right

After the ball becomes a dynamic ball, it is a no-ball foul to make illegal contact with the opposing team without the ball rights of both sides.

If a player commits a personal foul, if it is not a boxing foul, a malicious foul or an elbow foul, and neither side owns the ball at the time of the foul, it will be punished as follows: (1) register the fouled player as a personal foul; Register a foul team for team foul; If the team's foul penalty does not appear, the opposing team is sentenced to throw a foul ball on the sideline near the foul place; If there is a team foul penalty, the infringed player will be awarded a penalty plus points.

If the defender is convicted of a foul without possession of the ball, and then the shot (free throw) is successful, the fouled side should be fined, making it possible for him to score 3 or 4 points. This rule applies to: no matter which offensive player fouls; Regardless of whether the team fouls or not.

If the attacker is convicted of a foul without possession of the ball, and then the attacker succeeds in shooting, no points will be scored.

(4) Boxing foul

It is a boxing foul for an athlete to slam his opponent.

It is a personal foul and a team foul for a player to be convicted of illegal contact because of boxing. Should be awarded a penalty, regardless of whether the penalty is successful or not, should be awarded to the infringed team to throw a foul ball in midfield.

Any player who punches his opponent, whether he hits or not, is immoral. He should be fired immediately and stop at least one game.

This rule applies to the game in progress and the dead ball state.

If boxing fouls occur one after another, all the contents of this rule will be applied, and the team that was finally fouled will throw a foul ball in the midfield.

In addition, according to the situation, the player was fined not more than $20,000 and was suspended.

(5) Non-competition foul

In the last two minutes of the fourth quarter or overtime, the defender made illegal contact with the attacker with the ball, and this contact occurred in the area far away from the ball or when the foul ball did not leave, which was a non-match foul penalty: registered individual foul and team foul; A free throw (elbow foul or malicious foul twice) can be executed by any player on the field; And the infringing team threw a foul ball near the place where the game was interrupted to continue the game.

(6) Team foul

Each team fouls more than 4 times in each game, and each team fouls more than 3 times in overtime, and the penalty points are added.

If the team fouls less than 4 times within 10 minute before each festival, or less than 3 times within 3 minutes before overtime, the team is allowed to make a team foul in the last two minutes without additional punishment.

If the player who is shooting has a personal foul, he will be sentenced to two free throws, and if there is a team foul penalty, he will not be sentenced to additional free throws; If the shooting is successful, a penalty will be awarded, and if there is a team foul penalty, no additional penalty will be awarded. In other words, a successful two-point shooting can get up to 3 points, and a successful three-point shooting can get up to 4 points.
