Championship title winners Wolves will be backed by a sold-out away following for the season finale at the Stadium of Light.
But a request for more tickets for away fans has been rejected by Sunderland, who don't want to move season ticket holders to accommodate additional Wolves fans.
A total of 2,589 tickets were made available for the end-of-season clash on Sunday, May 6th clash and they were quickly snapped up.
Sunderland say they gave "full consideration" to the request but felt it would be unfair to relocate home supporters from their usual seats in the upper north west corner given it will be the final game before the Premier Concourse is closed next season.
The club also considered other areas within the lower bowl of the Stadium of Light but it wasn't feasible to safely allocate extra Wolves supporters.
A Sunderland spokesperson told the Express & Star: "We gave full consideration to this request when it was first made by Wolves a few weeks ago.
"To put some context into the issue, the away supporters are situated in the upper north stand at the Stadium of Light, the east end of the away section is the end of the stand itself.
"With this in mind, the only additional seats that logistically we could consider allocating to Wolves supporters were in the upper north west corner.
"This corner houses a significant number of Sunderland season card holders, many of whom have held their seats for many years.
"Given that these supporters will already be relocated when this area closes next season, we felt it would be insensitive to relocate them for the final match of the season.
"We did look at other areas within the lower bowl of the stadium, but again due to the presence of home season card holders there is no area we can safely allocate to Wolves supporters.
"We appreciate that this will be disappointing for our visitors, but we hope they understand that we made best endeavours to meet their request, but unfortunately is has not been possible for the reasons outlined above."
