At the other end, Steve Morison tries his luck with a well-struck volley but he fires over.

Then Bradford aim a deep cross towards Tony McMahon, but his header doesn't have enough power on it.

Meanwhile, Joe Martin comes off to be replaced by Millwall's Tony Craig.

Bradford are building more and more pressure, and they're still unhappy with the decision to deny a penalty a moment ago.

Now, Jamie Proctor has gone down in the box. There was some contact there, but did he throw himself down a bit too theatrically? The Bradford fans want a penalty. The referee - who was very well placed - says no.

Nothing comes of two consecutive Bradford corners and Steven Davies replaces Filipe Morais as they wait to take a third.

The hosts force a corner, down their left. Can they claw a goal back?

Millwall's first goal scorer, Lee Gregory, comes off to be replaced by Aiden O'Brien, the first substitution of the game. Gregory's fitness was doubtful before the match so they'll be pleased to have got over an hour - and a goal - out of the striker.

"I'm not sure what was said to him but Kyel Reid has come out a different player in this half. He really looks the part, he's going past his man and he's tracking back."

Bradford's Filipe Morais tries to find room to shoot in the area but his effort is blocked by the well-placed Mark Beevers.

Aiden O'Brien is getting ready to come on for Millwall, off the bench.

We still await the first substitution of this game.

Bradford have less than half an hour to try to avoid a first-leg defeat.

Millwall's Ben Thompson almost gifts Bradford an opportunity, miskicking a clearance and scooping the ball high into his own box, but they get it clear.

Tempers are flared up a little bit as Steve Morison jumps for a header with Nathan Clarke but appears to possibly lead with an elbow. The referee calms things down.

Bradford come forward again. They win another corner. They need to take advantage of this spell of pressure.

But the delivery is too close to the keeper and Millwall have a chance to slow things down a bit.

How did he miss that? Filipe Morais, what happened there?

The Bradford forward misses an almost open goal from seven yards. He had the angle, the keeper was badly positioned, but he side-footed wide, across the face of goal. BIG chance gone.

"The Bradford fans know that this game's not dead. They've seen their team come back from situations like this before and they know the role they play in this."

Bradford are giving this a go, there's no denying that. They need goals - and quickly. But they're yet to properly test goalkeeper Jordan Archer.

Bradford win a free-kick on the right and it is whipped dangerously into the six-yard box but Millwall get bodies in the way to block two shots and smother the danger.

Bradford have come out with an urgency and a willingness after the break. The early football at the start of this period is being played in Millwall's half.

Leaders Millwall, all in yellow, get this game going again.

Bradford had more of the ball in the first half but Millwall were far more effective with it when that had it.

Can the hosts change the one stat that matters - the score - after the break?

The players are back out on the field.
