As of today, penalty takers will not be allowed to halt after run-ups in an effort to fool the goalkeeper, after the International Football Association Board determined that it was not proper sporting behaviour, thus making it a yellow card offence ready for when the World Cup begins.
Jerome Valcke, from FIFA stated that while taking a penalty kick players will still be allowed to feint in order to confuse the goalkeeper, but feinting to kick the ball after the run up will be an offence.
If players still attempt to feint nearing the end of their run up and score a goal it will not count and they will have to take the kick over again.
The IFAB also decided this week that the fourth official will have more power on the field and to try a worldwide experiment with goal line officials.
Valcke stated that the fourth official will be able to rule on any incidents that occur on the pitch and that the fourth official is just as important as any other official out there on the field.
Despite the move on fourth officials, the decision to allow assistant referees into a game is still a voluntary decision.
After the trial finishes, federations and football associations around the rule are free to implement the new rules if they like, but are required to at least trial it during the World Cup.
The FA’s director of football services, Jonathon Hall, however stated it is unlikely that it will make it Scotland or England because it is not practical.
