which may include arguing with a referee, or commits a technical violation (delay of game, excessive time outs, or when a team has no eligible players remaining after a player has fouled out or subsequently the last player to foul out must re-enter the game, the latter two are NBA rules) that person may get charged with a more serious foul called a technical foul. In the NBA and in FIBA, a technical foul results in one free-throw attempt for the other team. Under NCAA rules, technical fouls are divided into "Class A" (violent or serious unsportsmanlike conduct) and "Class B" (less egregious violations such as hanging on the rim or delay of game). Class A technicals result in two free throws, and Class B technicals result in one. At all levels, the opposing team may choose any player who is currently on the court to shoot the free throws and is then awarded possession of the ball after the free throws. Since there is no opportunity for a rebound, these free throws are shot with no players on the lane. Finally, if a referee deems a foul extremely aggressive, or that it did not show an attempt to play the ball, the referee can call an even more severe foul, known as an "unsportsmanlike foul" in international and NCAA women's play or a "flagrant foul" in the NBA and NCAA men's basketball. This foul is charged against the player (who, depending on the severity of the offense, can even be ejected), and the opponent gets two free throws and possession of the ball afterward. Unlike technical fouls, the player fouled must shoot the awarded free throws. Fouls "away from the ball" (fouls that do not occur on the shooter or near the ball) are handled like the second case above in most situations. Many times defenders hold their opponent to prevent them from catching an in-bound pass or fight through screens and thus are called for fouls. These fouls are almost always treated as normal personal fouls. In the NBA, when there are only two minutes left on the clock of either half, off-ball fouls when the fouling team is over the limit are rewarded with one free throw and possession of the ball. It is therefore common for a losing team to deliberately single out its opponent's poor free-throw shooters, regardless of their dominance in other aspects of
