Newcastle United fans plan a sit-down protest against owner Mike Ashley after their final Premier League game against West Ham United.
The Magpies, in 17th and without a victory since 28 February, could be relegated if they fail to win.
The AshleyOut.com group said they "will continue to occupy the ground" after the final whistle whatever the result.
Manager John Carver said: "They can do what they want to do, but for 90 minutes get behind the team."
Ashleyout.com have also organised other protests against the owner in recent weeks, which included a fans boycott of the home game against Tottenham in April.
