The two teams will shortly be back out on the field, and Preston - leading 2-0 on aggregate - are 45 minutes from a Wembley final.

There's still plenty of life left in this one, though. However, you feel Chesterfield need an early second-half goal to give themselves the belief that they can get back into the tie, and I'm sure manager Paul Cook will have been emphasising that to his players while they enjoyed their half-time brew.

Of course, the prize for the winners of today's tie is a trip to Wembley on 24 May and a chance to play for a place in the Championship next season.

The other semi-final will be decided tomorrow night.

Swindon Town blunted the Blades on Thursday, sealing a 2-1 first-leg win at Sheffield United with a late goal from Nathan Byrne, who's buried under a mass of Swindon players in this picture.

So it looks like Preston are in control of this League One play-off semi-final, but promotion is far from assured for whichever team progresses at Deepdale today...

What do Chesterfield need to do to get back into this tie? Or is there no way back for the Spireites?

Jermaine Beckford's excellent finish divides the two teams. Heard that somewhere before? Well, this one's followed the same pattern as the first leg. A tight, nervy, tetchy first half, with a superb Beckford goal the difference.

Chesterfield winger Gary Roberts opens his box of tricks inside the area and puts a powerful low cross in towards the near post. John Welsh is back to divert it wide for a corner. And cleared off the line! Paul Gallagher is back to help out his defenders, keeping out Sam Hird's header.

Jermaine Beckford should probably stick to finishing and not tackling. Evidence of that as he goes in late on Daniel Jones and the Preston striker joins fellow front man Joe Garner in the book. Chesterfield whip the free-kick into the six-yard box but North End clear.

The match-winner in the first leg scores the opener in the second leg. A crucial couple of minutes in the tie, as Sam Clucas could have easily levelled for Chesterfield in the previous attack.

Advantage Preston.

It's that man Jermaine Beckford again for Preston, as he doubles North End's lead in the tie. He still had plenty to do from Joe Garner's flick-on, but Beckford rolls his defender and fires in from 10 yards past Joe Murphy.

That's 11 goals in his last 17 games for the on-loan striker.

"It was top goalkeeping from Sam Johnstone, who has kept Preston ahead. It was Schmeichelesque and when Sam Clucas looks up all he can see is a big green goalkeeper in front of him."

Certainly the biggest chance of the game so far. Will Chesterfield live to regret that?

Huge chance for Chesterfield, huge save from Sam Johnstone.

Sam Morsy sends Sam Clucas through on goal and Johnstone flies off his line to deny Clucas with his feet. Johnstone then claims the resulting corner under no pressure.

If things stay like this, Preston will be heading to Wembley on 24 May and facing either Sheffield United or Swindon in the League One play-off final. Chesterfield need a goal and almost create a good chance, as left-back Daniel Jones puts in an excellent low ball, but the lay-off from Sam Clucas only finds a Preston defender.

Having been clattered in the air by Joe Garner a few moments ago, Chesterfield defender Ian Evatt returns the favour and is booked. The free-kick comes to little but Preston still on the attack with a throw-in near the corner flag.

A second corner for Chesterfield, again on their right, and it's wasted once more. I always feel sorry for big, lumbering centre-backs in that situation - mainly because I used to be one. You race forward 60 yards in the hope of netting a rare goal, then trudge back solemnly having got nowhere near the ball.

"The niggling nature of the first leg seems to be continuing here, with some meaningful tackles going in from both teams.

"The managers are just as involved as the players - both Simon Grayson and Paul Cook are yet to sit down since the game kicked off, as they bark instructions at the edge of their technical areas."

There's a bit of needle between these two sides. Chesterfield's Jimmy Ryan was perhaps fortunate to remain on the pitch in the first leg after an apparent elbow on Paul Gallagher. Fair to say that a touch of ill-feeling remains between the two sets of players today.

Preston striker Joe Garner is the first man booked. His aerial challenge with Ian Evatt leaves the Chesterfield defender prone on the floor and referee Andy D'Urso takes his name.

Preston's Paul Gallagher sends in a curling shot from 25 yards but Joe Murphy is equal to it and saves comfortably. Murphy only signed for Chesterfield yesterday on loan, remember.

At the other end, Gary Roberts darts into the Preston box but loses possession.
