The 4th official keeps track of injury time
>>The 4th official keeps track of injury time
They do a horrible job of it. Last WC I used a stop watch to track how often the ball was in play (yes I know, not the same as injury time). It was only 68 minutes for a 90 minute match (+2 injury time).
Try it during a match sometime. You'll be surprised how little they actually play in a 90 minute match.
