Both clubs have issued messages urging fans to stay at home if the Old Firm fixture takes place, following criticism of Rangers response to last week’s title celebrations, which saw fans congregate at Ibrox and George Square.
First minister Nicola Sturgeon has welcomed the statements but added a final decision on whether the game will go ahead had not yet been taken.
Rangers have moved to further reassure the government by confirming a meeting with supporters groups.
The club tweeted: “Rangers can confirm that we met with supporters groups and key influencers this morning, in relation to the Old Firm game at Parkhead on Sunday.
“We are very pleased that our support is fully aligned on our messaging which has been underlined by both our manager and captain over the weekend.
“Stay at home. Stay safe. Support the NHS.
