With the sending off everyone keeps saying how does he get sent off for high 5ing a fan. However, the referee clearly points to 3 separate incidents when brandishing the card. I've seen the first one when he is near the corner as the goal goes in he runs to the crowd, but can't see if he goes over the boards. I've not seen the second incident, but the third one shown on the highlights he gives a high5 to a fan that is being reprimanded by stewards. Is the high5 not rewarding the fan for running on to the pitch?
