• The introduction of yellow and red cards for misconduct by team officials
• A player being substituted leaving the field at the nearest point on the boundary line
• At a goal kick and a free kick for the defending team in their own penalty area, the ball is in play as soon the kick is taken (it can be played before it leaves the penalty area)
Other changes include: clearer wording for ‘handball’, attacking team players must be at least 1m away from a defensive ‘wall’, the goalkeeper only has to have one foot on the goal line at a penalty kick, and a new dropped ball procedure (including a dropped ball being awarded if the ball hits a match official and goes into the goal, team possession changes or a promising attack starts).
