The match is currently in limbo after the passing of Queen Elizabeth II prompted the cancellation of all professional football fixtures across the UK this weekend, including Rangers trip to Aberdeen on Saturday.
Government guidance has left it up to individual sports authorities to decide whether fixtures should go ahead, and Rangers have confirmed that the club are in discussions with UEFA and Police Scotland over whether the match can take place as planned.
A club statement read: “At this difficult time for the United Kingdom, we are cognisant of ongoing uncertainty regarding supporter arrangements and travel plans for next week.
“We are aware of policing and resource pressures, especially on Tuesday, 13th September.
“We can confirm that discussions are taking place between UEFA, Police Scotland and Rangers regarding our scheduled UEFA Champions League fixture v Napoli on Tuesday, 13th September.
“As present, the game is scheduled to take place at the scheduled date and time.”
