Shelbourne want to withdraw from the deal to join Bohemians at Dalymount Park and have submitted a proposal to buy Tolka Park from Dublin City Council.
Shels bosses met with DCC earlier today over the issue, with a view to redeveloping their home in Drumcondra as a multi-sport stadium.
DCC bought Dalymount Park six years ago in a deal that got Bohs out of debts worth €7m.
