This is an example of a hand check foul. A defender cannot use an extended hand on a ball handler to illegally impede their progress, affect their balance and speed or delay their dribble. In this example, White 43 is set to start his dribble when defender Black 7 places his extended right hand on the right hip and arm of White 43. The illegal contact impedes White 43’s progress, affects his balance and speed and delays his dribble as he attempts to start a drive to the basket from the sideline. This is a hand check foul by Black 7 on White 43.
