For those who don't know, Billy collided with a concrete wall during Chichester's match at Wingate & Finchley FC in the Isthmian league. He suffered a severe brain injury & has passed away at just 21 years old.
I know quite a few on here frequent non-league fixtures & will know that concrete walls in close proximity to the pitch are commonplace at these levels.
It was very nearly fatal to Bath City's Alex Fletcher a couple years ago too & it's pretty clear something needs to be done.
