.. Unlike FIBA International, which has a maximum of 5 fouls per person per game, the NBA league uses 6 personal fouls before a player must leave the court. Of course, if a player receives 2 consecutive technical fouls in an NBA game, he will also be asked to leave the court directly by the referee. In addition, if a player receives one second-degree or two first-degree fouls, he or she will be ejected from the game. Serious cases will be further penalized by NBA officials after the game.
NBA and FIBA is different is the number of fouls off the court reason is that the NBA's regular playing time per game is 48 minutes, and FIBA games are 40 minutes per game, basically everyone's common fouls are allowed to be as often as 8 minutes a time, this point is the same for both the FIBA and the NBA.
In the same way as soccer, basketball and soccer both strongly encourage physical confrontation, so fouls are inevitable in the game. However, unlike soccer, basketball relies more on the hand position core for physical confrontation. Basketball was invented by James Nye Smith in 1891, and since then, the rules for calling fouls have become more and more sophisticated. the NBA referees are generally good, but there are a few specific games where the calls are not as good as they should be, and this often leads to controversy after the game.
Fouls in the NBA are categorized as common fouls (including defensive and offensive fouls), technical fouls, and malicious fouls (first-degree and second-degree fouls). Common fouls not only give the opponent free throws or exchange possession, but also accumulate for each player, and if the accumulation reaches 6 times, they will be sent off and can not play again in this game. Of course, technical fouls and malicious fouls are more severe penalties, but also for the protection of players and even coaches.
