The move means that Mackems in the Black Cats Bar and North Stand Upper, will have to be relocated to other parts of the stadium.
The decision to move the away section will "create a better atmosphere".
Wes Borgesson, of Seaham received his letter. “If I get moved to the South Stand I think it will be rubbish.
“I can see what they are doing, but I’m quite happy where I am.”
David Wilson,also of Seaham: “I’m surprised that we are having to move, I don’t see why we should be affected.
“I will be bothered about it if the seat we are moved to isn’t as good and maybe I wouldn’t renew.”
