Emil Riis forces a corner and Preston are really ending this half on the front foot.
It goes out for another throw, taken by Brad Potts as Preston push for another goal before the break.

Preston captain Ben Whiteman steps up to the spot and fires straight down the middle to draw Preston level with seven minutes to half-time.
Emil Riis is brought down in the area by Marvin Ekpiteta after getting in behind the Blackpool captain, and it's a stonewall penalty as the referee points to the spot.
