UEFA had ordered a similar closure for Thursday’s qualifying second leg match with Legia Warsaw after Rangers supporters were found guilty of sectarian singing in the previous round against St. Joseph’s on July 18.
European soccer’s governing body said the latest punishment was for sectarian chanting in last week’s goalless draw against Legia in the first leg in Poland.
Rangers advanced to the group stage of Europe’s second-tier club competition with a 1-0 aggregate win.
The UEFA Control, Ethics and Disciplinary Body ruled on Friday that Rangers must again close a section of their stadium containing no fewer than 3,000 seats.
They must also display a banner with “#EqualGame” and the UEFA logo on it in their next home match.
Rangers said on Wednesday that they would not be requesting tickets for their next European away match.
They were drawn with Portugal’s Porto, Switzerland’s Young Boys and Dutch side Feyenoord in Group G during Friday’s draw.
