Blades have work to do - Blackwell
The first leg ended 1-1 at Deepdale on Friday with the Blades creating the better chances and many observers felt Blackwell's side had seized the initiative ahead of the return leg.
But Blackwell warned: "It is 50/50 and no more, particularly as neither of us has a goal advantage which would affect things much more.
"Expectations have increased, but I have warned the lads that the job isn't done.
"When I was at Leeds we only drew at home to Preston in the play-offs, but then won the away leg at Preston.
"They have the players to be able to do that and this tie is wide open - we have just got to keep playing like we have since Christmas."
