Rangers were sanctioned by UEFA on Tuesday after fans held up a "discriminatory" banner during a Europa League game against Fenerbahce, with the Scottish club saying it was in the process of issuing lifetime bans to those responsible.
The Glasgow giants were told it would have to close its famed Copland Stand for one match if there were any repeat acts of racist and/or discriminatory behaviour within two years.
Rangers last week condemned their own fans after a banner which read: "Keep woke foreign ideologies out -- defend Europe" was raised during the game against Fenerbahce earlier this month.
"This punishment must serve as a severe and significant reminder to the small minority of supporters who bring the name of Rangers into disrepute," the 55-time Scottish champion said in a statement Tuesday.
"Not only will the reputation and finances of the club be harmed by such a punishment, but the chances of the team in a potentially key European match will also suffer enormously, while thousands of innocent fans will be unable to attend a massive fixture.
"In response to the displaying of the racist and/or discriminatory banner at the Fenerbahce game, the club can confirm that it is in the process of issuing lifetime bans to the individuals responsible."
As well as the suspended partial stadium closure, Rangers were fined 30,000 euros ($32,400).
It added that "illicit songs" would also be considered racist and/or discriminatory in terms of further UEFA action.
The Copland Stand is known as the "Rangers end" and is an iconic section of its Ibrox stadium.
Rangers advanced to the quarterfinals of Europe's second-tier Europa League by defeating Fenerbahce on penalties.
But the banner incident has cast a cloud over that achievement, with Rangers saying it was "deeply saddening and frankly embarrassing that the club is now set to face significant sanctions for the actions of a very small minority."
Rangers were also fined 4,500 euros ($4,900) for the throwing of objects and a further 8,000 euros ($8,650) for improper conduct of its players.
