With the first Steel City derby of the season taking place on Friday night at Bramall Lane (7.45pm), the Owls are reminding supporters of safety issues ahead of the game.
Our full allocation of tickets sold out almost immediately and we urge Wednesdayites not to travel to S2 without possession of a valid matchday ticket.
We are also underlining the consequences of any supporters attempting to ignite any form of pyrotechnic device.
Last week, ahead of bonfire night, the EFL re-launched its commitment to tackle the use of pyrotechnics, which includes smoke bombs, flares and fireworks within EFL football grounds.
This was initially launched in November 2017 that saw all 72 clubs sign up to a new Club Charter on Pyrotechnics.
Since the Charter was signed EFL clubs have been taking strong and decisive action against any fans found attempting to bring a banned item into a ground, or those who discharge pyrotechnics.
Any supporter that has been, or found to be, in breach of the terms of the Charter is subject to a minimum three-season club ban.
A number of club bans have already been issued since the launch of the Charter, including an increase in sanctions for away supporters due to the ongoing co-operation between EFL clubs.
Finally, the eyes of the football world will be on the televised derby encounter so we respectfully ask supporters to represent our club in the best possible way.
Thank you for your co-operation.
