Being at the game and a devout Waccamaw supporter, the situation is as simple as this.

The keeper made a good play to make the block but the forward did nothing wrong as she was going for the ball in an attempt to score. Neither player did anything illegal and it was just unfortunate that the ball rebounded out to another Bishop England player. She placed her shot well and it turned out to be the game winner. Had the keeper been able to get right back up after the collision she still would not have saved the shot. In the end, it's unfortunate but completely legal and the referee made the correct decision.
