replace
Substitute players should report their names and numbers to the recorder and stay in the replacement area in front of the recorder. If you don't report to the recorder, you will be fined $25. When the ball becomes a dead ball (except after the successful shooting), the recorder will whistle to announce the substitution, and the substitute players need to be signaled by the referee to enter the game. The time to replace a disqualified player is 30 seconds.
After the first free throw of many free throws, substitutes are allowed to enter the game regardless of whether the free throw is correct or not.

Once the substitute enters the game, he must stay on the field until the next dead ball.
If a player is injured due to unethical behavior and cannot execute a free throw, his coach can designate any qualified player in the team to execute a free throw. Injured players can also play again.
pause
(l) Pause for 20 seconds
Every half hour, each team has the right to ask for a 20-second timeout. Each game (including overtime) can require two 20-second timeouts.
A player asks for a 20-second timeout, which will only be suspended when the ball is dead or the team has control of the ball. Players should shout "20-second timeout".
During the 20-second timeout, the team can only change one player. If the suspended team is asked to replace a player, the opposing team can also replace a player.
If a second 20-second timeout is required at halftime (including overtime), it should be allowed, but the regular timeout should be registered.
If the game cannot continue at the end of 20 seconds, you should also register for a regular timeout.
(2) Regular pause (100 second)
Each team has the right to request a regular suspension of registration for 7 times. The fourth quarter limits each team to no more than 4 timeouts; In the last two minutes of the fourth quarter, there shall be no more than three pauses. In overtime, each team is allowed to pause three times.
The player requests a time-out of 100 second, which will only be given if the ball is dead or the team controls the ball. Players should shout: "Time out".
There must be two pauses in each game. If no team calls a timeout with 6 minutes and 59 seconds left in each game, the recorder should take a mandatory timeout at the first dead ball, and this timeout should be registered in the name of the home team. No team calls a second timeout when there are 2 minutes and 59 seconds left in each game, and the recorder has to force a timeout when the ball is dead for the first time. This timeout is registered in the name of the team that has not been registered in this section before.
Additional timeouts are allowed, but a technical foul will be awarded. When the game is suspended, the head coach can ask for a 20-second or 100-second timeout.
Rule number two
When a team gets a new ball in a game, or when the ball is thrown into the field and legally touched by the players on the field, the 24-second timer will start counting. The team that owns the ball must shoot within 24 seconds after getting the ball. The conditions for completing the shooting are:
(1) Before the end of 24 seconds, the ball must leave the player's hand;
(2) After the ball leaves the player's hand, it must touch the basket itself.
If the ball doesn't touch the basket within 24 seconds, it's a 24-second violation.
Basketball is divided into foul and foul. When a player fouls six times, he will be sent off. If a player is fouled twice before six fouls, he will be sent off. When the team fouls four times per quarter, the fifth foul will lead to two free throws. Violators will not be sent off, but the ball will be given to the opponent.
8. Evil
(1) Offensive foul
After the ball survived, the attacker made illegal contact with his opponent. (that is, the defender has stood outside the reasonable collision zone and his feet have not moved. After the attacker knocks down, it is an offensive foul. Accordingly, if the defender moves, it is a defensive 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).
(2) Moving pick-and-roll foul
When carrying out pick-and-roll tactics, the pick-and-roll players should stand still, keep their feet still and keep a certain distance from the defenders, otherwise they will be blown to make a pick-and-roll foul.
(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) 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. 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.
9. Violate the law
(1) Go: Hold the ball for more than three steps, and you can't go.
(2) Stuck: When the ball thrown by the opponent reaches the highest point and begins to descend, the defender will be blown into a stuck ball when he touches the ball, and the attacker will be punished for scoring directly, and the ball will be handed over to the defender.
(3) three-second violation:
Defensive three seconds: It means that the defender stands in the three-second zone around 1 m without attacking players, stays in the three-second zone for more than three seconds, and defensive three seconds violates it twice in three seconds, which is regarded as one penalty and one execution.
Attack for three seconds: it means that the attacker stays in the three-second zone without the ball for more than three seconds or has an offensive action or intention, which is regarded as an attack for three seconds and will be punished by exchanging the ball rights!
(4) Violating the serve for five seconds:
When serving a foul ball, you should serve it within five seconds, otherwise you will be punished and the ball will be handed over to the opponent.
(5) Eight-second half-court violation:
That is, at the beginning of the attack, after taking the ball from the backcourt, it is necessary to transport the ball across the half court to the frontcourt within 8 seconds, otherwise it will happen for 8 seconds.
(6) Two dribbling violations: that is, holding the ball after the first dribbling, and then starting dribbling again, which is called violation, and awarding the ball to the opponent.
(7) Wrist turning: Now it is a very tight violation in the NBA. When dribbling, the vertical angle between the palm and the ground is not allowed to exceed 90 degrees, which is called wrist turning. Actually, it's about the same as two dribbles. When dribbling, hold the ball with one hand and dribble once.
