This is an example of a Flagrant Foul, Penalty 1. A Flagrant Foul, Penalty 1 is defined as contact that is unnecessary. The defensive player on this play grabs the arm of his opponent and he pulls him down to the floor with his follow through. This is a non-basketball play toward a vulnerable player with a high potential for injury. The penalty for a Flagrant 1 is two free throws for the offended player, and his team would also retain possession of the ball. Note also that any called foul that could potentially be ruled flagrant will be reviewed via Instant Replay, to determine if it is a Flagrant 1, a Flagrant 2, a Technical Foul, or a common foul.
