Following discussions with Morecambe, 600 more tickets have been allocated for Blues fans.
Morecambe and Southend United have come to an agreement for another 600 tickets to be allocated for Blues fans for the game against the Shrimps on Saturday.
This means Blues fans will now be able to purchase tickets for Morecambe's North Terrace.
Blues Chief Executive Steve Kavanagh said: “I would like to thank Morecambe Football Club for granting our request for extra capacity.
“Their kind gesture will allow so many more Southend fans the opportunity to be present for what we hope will be a memorable day in their Club’s history.”
There is now a waiting list due to the high demand for tickets and if your name is on the waiting list and there's a ticket available, the Blue Box Office will give you a ring.
Tickets are NOT available on the day at Morecambe.
