Agreed...what hurts initially isn't always a serious injury...sometimes it just takes a minute to shake it off. With sportsmanlike teams, if they realize a player isn't getting up and isn't being attended to by the officials, the ball will be kicked out. Prominent example and compliments to the Stratford High girls last year when we played them--I had a player go down hard and not move. The center ref did not stop play, which was in our defensive third, and yelled "play on" when he was directed to the girl who still had not moved. The entire Stratford team simply stopped and refused to go to the ball despite advantage and repeated calls of "play on" until we finally got a whistle...great example of sportsmanship and class.
