Additional time is allowed for a penalty kick to be taken and completed at the end of each half of the match or extra time.
When additional time is allowed,
the penalty kick is completed when, after the kick has been taken, the ball stops moving, goes out of play,
is played by any player (including the kicker) other than the defending goalkeeper,
or the referee stops play for an offence by the kicker or the kicker's team. If a defending team player (including the goalkeeper) commits an offence and the penalty is missed/saved, the penalty is retaken
