应该不是新规则吧。但Unsportsmanlike Foul好像是2004年被国际篮联确认的。
“违体犯规”是国际篮联的术语,Unsportsmanlike Foul;在NBA叫Flagrant Type 1 Foul。
Flagrant fouls and game tactics
Within a game, the presence of the flagrant foul rule helps to deter undesired play (usually as the game winds down) by awarding possession of the ball as an extra penalty. A simple personal foul or intentional foul will generally result in either free throws or possession of the ball depending on the number of accumulated team fouls at the end of the game. However, a flagrant foul will result in both the award of free throws and subsequent possession. Thus, when a trailing team is employing a tactic of slowing the game down by fouling, it must be careful not to use unnecessary or excessive contact, even though such fouls are intentional by definition, or it will give its opponent both free throws and the ball back and defeat its own tactic.
