An extra 545 tickets have been made available to Coleraine fans for the IRN-BRU League Cup final against Crusaders at the Ballymena Showgrounds.
Demand for tickets for the 28 January decider exceeded expectations and Coleraine's allocation of 1750 tickets sold out within three days.
Temporary seating will be installed behind one of the goals to accommodate the additional Bannsiders supporters.
The Crusaders allocation of 1300 is expected to be snapped up.
The IFA also considered moving the game to Windsor Park to meet demand.
Both clubs agreed to the choice of the Showgrounds as the venue for the final but health and safety considerations and security procedures limited the capacity of the stadium.
