Sam Dalby is on a one-v-one with the keeper but Preston stopper Daniel Iversen judges the strike well and dives right to deny Bolton a third goal.

Max Conway's cross into Josh Sheehan is nice but the latter's strike at goal is easily mopped up by Preston keeper Daniel Iverson.

Milutin Osmajic is in the box for Preston and is able to slice at goal but it catches a deflection to take it away from the target.

Those changes appear to have flipped a switch for the visitors.

To see Leo Leroy and Jusef Erabi come on, those changes have given the Preston fans a lift.

We've got a triple change from Preston to try and halt Bolton's momentum.

Leo Leroy is on for his debut having only signed for the club yesterday. He's joined by Odeluga Offiah and Jusef Erabi.

Jordan Thompson, Callum Lang and Pol Valentin depart.

Thierry Gale curls at goal but it goes just wide of the corner.

Preston are allowing the Bolton winger so much space. Gale's had so much opportunity today and while he's only punished once so far, it feels a matter of time before he'll do it again.

Alfie Devine sets up Delano Burgzorg but Bolton's Luca Stephenson makes a timely challenge.

The right-back has hurt himself in the process though and requires treatment.

John McAtee started seven times for Bolton in League One last season.

He's been excellent today.

Thierry Gale crashes a shot into the top stands after Preston lose possession in their final third.

Not for the first time, North End can exhale.

We've seen more of Alfie Devine in the opening six minutes of this second half than we did in the entirety of the first, or at least it feels that way.

He gets his right foot on the ball but his volley goes awry and off target.

Better signs for North End all the same.

Preston's free-kick is over-worked and they can't get the shot off but with so many red shirts up field, Bolton spot a chance to counter.

A ball is sent up to John McAtee and he thrashes at goal but it's sent wide. A nice try, though.

The yellow card is brought out but not for a Preston player for a change.

Alfie Devine begins his move forward and is tripped up by Josh Sheehan to win a free kick.

Can Preston do anything to stop Bolton's runaway train?

They were rattled in the first half but trail by only two goals. A comeback can be done.

Let's see, shall we? The game is back up and running.

It wouldn't surprise me if Paul Heckingbottom makes changes and their shape.

Bolton just look hungry on the front foot.

Preston have been too far off the pace and Paul Heckingbottom will not be happy.

They can't be that bad in the second half. They have to play with more energy and belief.

Bolton haven't won against Preston since the 2001 Division One play-off final but they look good to break that spell today at the break.

Four shots of eight on target from the Trotters, with Sam Dalby and Thierry Gale's both finding the back of the net.

Preston, meanwhile, are offering up nothing.

For those who were writing off Bolton this season, they have something to say.

Just one minute until half time after Bolton cut out a threatening pass to Preston front man Milutin Osmajic.

I'm just thinking if Paul Heckingbottom is thinking about introducing Leo Leroy at half-time for Preston?

Another yellow card for Preston. Might start getting precarious soon.

This one belongs to Pol Valentin, who is finding Thierry Gale a real challenge this afternoon and has now gifted the Bolton man more leeway.

Preston put together a clever set play but it doesn't pay off as Andrew Hughes' header is blocked and the ball is back up the other end.

Thierry Gale tears it up on the left, sliding the ball to John McAtee whose attempt from just outside the box flies too high.
