There are a lot of if's here in this post.It started with stoppage time and is now into the restart of play for an injury. Maybe the referee did not see the injured player until Chapin moved the ball into its attacking third. The referees procedure was correct. Team in possession at stoppage, Indirect free kick. Or if the referee thought it was a head injury, maybe that is why he blew the whistle when he did. I was not there. Referees are to side on caution when it comes to player safety. IT IS A MUST. And talking about sportsman ship about playing the ball back.....well Chapin had the ball and referees, in HS, at a free kick, can not tell them to play the ball back. Maybe the referee blew the whistle too early. Think about it. Chapin had the ball attacking, and a chapin player was down. As a referee i would let play continue until 1 of 2 things happen. Player down becomes involved in play or the ball leaves the field over the goal line or the touchline. My 2 cents.
