Football authorities in the North were today introducing a new code of conduct in a bid to silence the bigots on the terraces at Northern Ireland home internationals.
The move, to be announced in Belfast, follows the sectarian abuse directed at Glasgow Celtic star Neil Lennon during last month's friendly at Windsor Park.
The code is among a package of unprecedented measures to be announced by the Irish Football Association, which was left hugely embarrassed by the sectarian chants from a section of the crowd.
IFA community relations officer Michael Boyd said the plans were an attempt to cut out foul, abusive or racist language and unruly behaviour among spectators.
He said: "If they don't abide by the code of conduct, they are going to be ejected from the stadium and banned from Northern Ireland games."
Anyone who buys tickets for Northern Ireland's next home match against the Czech Republic on March 24 will receive a copy of the code.
Thousands of specially designed cards will also be distributed at the turnstiles for fans to show their backing for the team.
Imploring supporters to give bigotry the red card, the crowd will be asked to brandish them during the game.
IFA president Jim Boyce described the plans to rid the game of sectarianism as the most far-reaching changes ever made to football in Northern Ireland.
