I was at the game and saw the play. It looked as if #10 was attempting to block the BHS cornerback, but got taken to the ground during the process. The whistle blew and #10 gets up and then smacks the BHS cornerback across the helmet, while the ref is standing right on top of the play. Obviously I couldn't hear the interaction between him and the ref, but it did appear he said something to him after the first flag was thrown.
Either way...it was an unfortunate ending to a well-played game.
