Alex Morris says supporters who carry smoke bombs or pyrotechnics are not welcome at Crewe Alexandra matches.
The Manager maintained the club's firm stance against a tiny minority of fans who appear determined to spoil fixtures by bringing illegal and dangerous items into stadiums.
The Railwaymen's super opening-day victory at Rochdale was marred when the game had to be paused to allow medics to treat an Alex supporter suffering from the effects of smoke inhalation.
Fortunately, that person recovered, but it is sadly not the first time that we have seen smoke bombs or pyrotechnics set off by Crewe followers.
"Our supporters are absolutely fantastic, both in terms of numbers and how vocal they are," said Alex, who is preparing his team for the first home match of the campaign against Harrogate tomorrow (Saturday, August 6, 3pm).
"Unfortunately, we are struggling to shift a small minority who are using pyrotechnics and smoke bombs and it will cost us in the end.
"The football authorities have made it clear there will be repercussions. So I’d urge those people not to come to games if they can’t come without bringing those things, because not only will it have repercussions for the club but also people can be hurt or have their health affected.
"I’m glad to hear that person is well and managed to return for the second half (at Rochdale), but it has to stop. It has happened a few times now."
The Premier League and EFL are cracking down on the issue. Under new rules, individuals who carry or use pyrotechnics or smoke bombs will be banned and those identified reported to the police.
Crewe Alexandra signed the Club Charter on Pyrotechnics in 2017, which includes a commitment to take strong and decisive action against any fans found attempting to bring a banned item into a stadium, or those who discharge pyrotechnics.
The Club wishes it to be known that any supporter found in breach of the terms of the Charter will be subject to a ban.
