Fans attending Saturday's Sadler's Peaky Blinder Irish Cup tie between Queen's University and Glentoran have been warned about potential counterfeit tickets being in circulation.
The sixth round clash is being played at the Dub which has a limited capacity.
Glentoran have only been allocated 100 tickets for the match, which the East Belfast club distributed through a raffle.
The Oval giants - whose average home attendance exceeds 2,000 supporters - have issued advice to those fans who have a ticket for Saturday's cup tie.
"The club has been informed that there have been reports of counterfeit tickets available for our Sadler's Peaky Blinder Irish Cup tie at the Dub on Saturday," Glentoran said in a statement.
"As a result, Queen's University FC have asked that each of the 100 Glentoran supporters who were successful in the draw for tickets please report to the reception at the Dub when they arrive, to show their season ticket as well as their match ticket.
"No one will be able to gain entry without proof of identification.
"Also, supporters who hold tickets for Saturday's Irish Cup game at Queen's University should note that they must retain their ticket stub when using the bar and toilet facilities as there will be no re-entry to the ground without this."
