I don’t remember the last game it was used but I do recall them using some kind of black cladding across the stand minimising capacity for a bit.it was a health and safety risk the stand was falling apart.
He booted the advertisement board with some force when he hit the bar at Stevenage I wouldn’t be surprised if he triggered something doing that.stupid.
