Rangers have agreed to give Celtic fans the Broomloan Road stand for the upcoming Scottish Cup quarter-final tie on 8 March.
It means about 7,500 away fans will have access to an Old Firm derby at Ibrox or Celtic Park for the first time since 2018.
The decision was taken after consultation between both clubs and the police.
Away supporter allocations have been limited to around 800 tickets in recent derbies following a period of no away fans at the fixture.
It is believed Rangers reached the decision after assurances Celtic would reciprocate for any upcoming cup matches at Celtic Park. Scottish FA rules state away clubs should be entitled to a 20% supporter allocation.
