In the Laws of the Game, Law 12 states that denying an obvious goal-scoring opportunity (DOGSO) has two different punishments, depending on the outcome of the play.

But let's start by defining what DOGSO is. The law says it's when "a player denies an obvious goal-scoring opportunity to an opponent moving towards the player’s goal by an offence punishable by a free kick (direct or indirect) or a penalty kick."

The interpretation of the punishment is important as well. The law states, "If the referee makes use of the advantage during an obvious goal-scoring opportunity and a goal is scored directly, despite the opponent’s handling the ball or fouling an opponent, the player cannot be sent off but he can still be cautioned."

In that case, a yellow card is warranted, according to FIFA. If the opponent does not score, however, it is a send-off offense.

In today's referee review, we'll take a look at four videos and see how MLS referees interpreted the rule.
