The punishment follows a charge of "racist behaviour (sectarian chants)" by fans during the club's match against Legia Warsaw on 22 August in Poland.
European football's governing body has ordered Rangers to leave 3,000 seats empty for their next European home match. They must also display a banner with the wording “#EqualGame”, and the Uefa logo on it.
The punishment is identical to the one meted out to the Ibrox club for a similar charge following sectarian chanting against St Joseph's in an earlier round of this season's Europa League.
That led to Rangers having 3,000 empty seats for Thursday night's home game against Legia Warsaw, which they won 1-0 to secure their place in the group stage.
• The Scotsman published a story online this morning which stated that Rangers were facing a third charge from Uefa over sectarian singing.
We accepted the story from a trusted and experienced freelance in good faith.
However, we quickly discovered there was no third charge and we took the story down from our website immediately.
We would like to offer our sincere apologies.
