If a player, coach, or team staff (e.g., doctor, statistician) shows poor sportsmanship, 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, a technical foul results in one free throw attempt for the other team. In FIBA play, technical fouls result in two free throws in all situations. 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.
