A corner is awarded if the ball goes over the back line after last
being touched by a defender, provided they do not play it over the back
line deliberately, in which case a penalty corner is awarded. Corners
are played by the attacking team and involve a free hit on the sideline
5 m from the corner of the field closest to where the ball went out of
play. These restarts are also known as long corners (as opposed to short
corner which is an alternative name for the penalty corner). The
defense must wait until the offender passes the ball in. The offender
has to pull the ball out of the circle before trying to make a goal.
