'There were dramatic scenes at the stadium ahead of the game as Leicester City paid their tribute ahead of Remembrance Sunday. The match ball was brought into the stadium and presented to referee Clive Penton by helicopter.
An AS350 single engine Squirrel helicopter, currently in service with the Defence Helicopter Flying School, descending into the stadium around 2:50 p.m. The crew were Captain M W Westwood of the Royal Navy and Flt Lft C M Smith of the Royal Air Force.
It was superbly received by the crowd as it landed in the centre circle, before Captain Westwood made the presentation of the ball. As it then ascended out of the stadium it turned to all parts and even took a bow. To add to the rememberance, the home side had poppies stitched to their shirts.'
