Preston defender Bailey Wright gives away a cheap corner, the first of the match. But it's an awful delivery from Gary Roberts, who is capable of much better with that wand of a left foot he possesses.
Preston starting to build some momentum now, and Chesterfield finding it difficult to get out of their own half. However, North End are yet to seriously test Joe Murphy in the Chesterfield goal.
Tensions start to rise as North End striker Joe Garner is brought down by Daniel Jones, and there's a bit of afters between the two. The referee has a quick word with the pair, but no cards. Paul Huntington heads Daniel Johnson's free-kick straight at Chesterfield debutant Joe Murphy.
Appeals for a Preston penalty as Jermaine Beckford, with his back to goal, goes to ground inside the box under pressure from Sam Hird. Referee Andy D'Urso having nothing of it and waves play on.
A cross in from Paul Gallagher on the Preston left is aimed towards Jermaine Beckford but the striker is muscled out of it by the Chesterfield defence.
A bit scrappy for a couple of minutes as Preston look to get a foothold in the game, but their prolific front two of Jermaine Beckford and Joe Garner have been starved of service thus far.

"You've got to produce on the big stage - that's the difference between the best players and the average players.
"Chesterfield are dominating the ball and, at the moment, are out-witting Preston."
Another good move from Chesterfield, who work it to the left and Gary Roberts' drilled cross is cleared by the hosts. If anyone thought Simon Grayson and Preston would cruise to Wembley, think again.
Yani Kapitanov: Really want Preston to get promoted. It's easier to watch Championship from Bulgaria and Preston are my second favourite team.
Decent ball in from Daniel Jones on the left is easily cleared by Preston. Bright start by Chesterfield, though.
Chesterfield have got to do what only Bradford have done in League One this season - win at Deepdale. And an early chance for the visitors! But Sam Clucas fires wide from 20 yards.
Referee Andy D'Urso blows the first whistle and we're under way at Deepdale! A place at Wembley in a fortnight's time is at stake.
The two captains - Tom Clarke of Preston and Sam Morsy of Chesterfield - lead out the teams at Deepdale and we're nearly ready for kick-off.
Preston are a goal up from the first leg. And remember, we could need extra time and penalties to settle this one.
Chesterfield boss Paul Cook told BBC Radio Sheffield:
"If we can start in the correct manner then we have a major part to play in this tie.
"The next goal will be vital and if we were to score next and take control, they could come under real pressure. If they get it, it could become a carnival atmosphere.
"We have their respect and they have got ours."
Preston boss Simon Grayson told BBC Radio Lancashire:
"What we've got is belief - the lads showed character and spirit after a lot of criticism.
"They've stuck their chests out like we asked them to do and come up with the goods.
"We've got to make sure we do exactly the same thing on Sunday now."
Kevin Davies was an unused substitute for Preston in Thursday's first leg, and he takes his place on the North End bench again today.

You only have to walk around Deepdale to get a sense of Preston North End's rich history.
"The Invincibles" - so called after winning the double and going through the whole of the 1888-89 season unbeaten - have a lounge named after them inside the stadium.
Sir Tom Finney, the club's most famous player and Preston's favourite son, is honoured with an iconic statue that stands proudly outside the ground.
The current crop of North End players would have to go a long, long way to match their respective achievements. Ending the club's horrendous play-off record would be a start.
You have to go all the way back to the 1950-51 season for the last time Chesterfield played in the second tier of English football.
