Hearts have warned that the home match against St Mirren on November 17 could be their last game, while imploring fans to to buy tickets and subscribe to a share issue to help fend off a winding-up order over a £450,000 tax bill.
And Deans has joined calls for supporters to heed the plea for emergency backing.
He said: “The reality is, leave aside whose fault it was, leave aside responsibility for it, the important thing is to save Hearts from going to the wall.
“Hearts have been around, they have been an important part of the fabric of Scotland’s capital city for 136 years. Hearts cannot be allowed to die.”
