Leeds United head into the break trailing 1-0 against the Championship's bottom club Blackpool courtesy of a Gary Madine header on the stroke of half time.
The visitors started on the front foot and fired a warning shot in the second minute as Luke Murphy struck wide, but it was the hosts who came closest in the opening stages.
Andrea Orlandi played a dangerous ball across the six-yard box with eight minutes played, and Michael Jacobs came within inches of making a connection and putting Blackpool in front.
Orlandi was a thorn in Leeds's side throughout the first half, and he sent their nerves jangling again in the 25th minute when his dangerous free kick was almost turned in by Madine.
Early warnings went unheeded and Leeds fell behind from another set piece one minute before half time, Orlandi's initial effort coming back off the post and Madine heading home to give Lee Clark's side a surprise lead at the interval.
