Hearts chiefs have been left "very disappointed" after a request for 50-50 ticketing for the Hampden showdown against Rangers was denied.
The Tynecastle club has been handed an initial 18,000 ticket allocation for the Viaplay Cup semi-final - with the possibility it could rise to 20,000.
However, Hearts chiefs had requested an even split of the tickets for the fixture on November 5 but had it turned down with Rangers given an increased allocation.
A club statement reveals the reason for the rejected 50-50 ticket appeal came down to "previous sales history" and the "inability to segregate Hampden's North Stand into subsections".
Hibs and Aberdeen's semi-final contest on November 4 will see the ticket allocation split down the middle.
A Hearts statement confirmed: "Ticketing details for Hearts’ Viaplay Cup semi-final match against Rangers have been confirmed.
"The Jambos will meet the Glasgow side at Hampden Park on Sunday, November 5th at 3pm, with the game being broadcast live on Viaplay.
"Hearts supporters will be housed in the National Stadium’s South and East Stands, with an initial allocation of 18,000 which may rise to 20,000.
"The club would like assure fans that we requested and pushed for an even 50-50 split of tickets, but due to previous sales history and the inability to segregate Hampden’s North Stand into subsections, this request was denied.
"Naturally, we are very disappointed at this outcome but we are confident that Hearts supporters will take up our full allocation and turn Hampden into a sea of maroon.
"Tickets start from £28 per adult and £12 for Over 65s/Under 16s."
