Rovers have decided they cannot afford to loan the teenager despite initial talks with the Dons.
But Aberdeen manager Craig Brown is confident of adding to his squad today.
"We are still pursuing a player, we think by the deadline we should have something done," Brown said.
"This is a defensive player, a midfield player who can play at the back. He is based in England but has experience in Scotland, he`s a respected player. It`s 90% certain.
"It`s not Jason Lowe, we were interested in him but he is required by Blackburn. He was on the bench on Saturday, they have a couple of midfield players injured."
