Whatever it takes, to stop 'theatrical play' needs to be done. Since it is so prevalent internationally (not in MLS, college, etc.), it would have to be handled by FIFA. But hopefully they would not go overboard like they did with the ref instructions on fouls this year. This would have been a great Cup to address the 'theatrics' issue, rather than the fouls issue. One way to address the fake injuries would be to not stop play if the ball is out of the 'injured area', and not stop play until a team kicks it out on purpose or at the next normal stoppage of play. I may be mistaken, but there are probably only a certain few players who consistently play the 'theatrics' game. Those players could be warned informally by FIFA to clean it up or face disciplinary actions off the field, in addition to being watched closely by the fourth official during matches.
