When a penalty corner is awarded, a maximum of five defending players (including the goalkeeper) line up behind the back line either in the goal or on the back line at least five metres from the ball. All other players on the defending team must be behind the centre line. One attacking player places themselves on the back line, with the ball in the circle at least 10 metres from the nearest goal post on either side of the goal. The remainder of the attacking team players place themselves on the field outside of the shooting circle. All players other than the attacking player on the back line must not have any part of their body or stick touch the ground inside the circle or over the centre line until the ball is in play. The attacking player on the back line is allowed one foot within the circle, but the other foot must remain behind the back line. If any player enters the circle or crosses the centre line prematurely, or the attacking player on the back line does not have one foot outside the circle, the penalty corner is reset and taken again.
